Mapping the Midterms: Key Races to Watch for a Potential Democratic 'Blue Wave'

Midterm elections historically present challenges for the president's party, with outcomes ranging from difficult to historically detrimental. As Tuesday's elections approach, Republicans are expressing concern about a potentially difficult night, while more Democrats are anticipating a significant victory. Recent polling data largely favors the Democrats, suggesting that attitudes towards the current president are a primary driver of midterm results. President Donald Trump's current approval rating is significantly lower than those of previous presidents before their parties experienced substantial midterm losses, including in 2018 when Republicans lost over 40 House seats.

Surveys conducted in the final days of the campaign indicate Democratic strength in traditionally Republican-leaning states such as Texas, Ohio, Kansas, and South Carolina. However, the concentration of competitive races in Republican-dominated areas leaves many Democrats feeling apprehensive, particularly regarding the Senate. In most contested states and House districts, Republican voters still outnumber Democrats. If President Trump's campaigning and substantial Republican spending can mobilize voters beyond current expectations, it could diminish the narrow Democratic advantages in these red states.

Paul Maslin, a veteran Democratic pollster, noted, "The best news for our side is that the vaunted Republican surge at the end that many would have expected given all their money just hasn’t happened." He added, "In these double-digit red states, it’s simply a case of are (our leads) baked in enough for us to pull through?"

This guide identifies House, Senate, and governor races that will serve as indicators of the election night's direction, moving from East to West. These races are categorized by their potential to signal a good night, a very good night, or a historic breakthrough for Democrats, comparable to the Republican landslides of 1994 and 2010, or the Democratic "thumpin'" in 2006. Conversely, if Democrats falter in several races categorized as "good," it could signal a disappointing outcome.

The Northeast

The initial indicators of the night will emerge from the Eastern region due to the earliest poll closings. In Virginia, a Democratic win in the VA-2 House race, where former Rep. Elaine Luria is challenging Republican Jen Kiggans in a district Trump carried by less than a point in 2024, would suggest Democrats are on track for a solid performance. Failure to win this race could be an early sign of Democratic underperformance. A Democratic victory in the VA-1 congressional seat, where Republican Rob Wittman faces Democrat Shannon Taylor in a district Trump won by five points, would further indicate a larger wave.

If former Democratic Rep. Tom Perriello unseats Republican Rep. John McGuire in VA-5, a district Trump carried by 12 points, it would signal Democrats are on pace to exceed their 2018 total of 235 House seats, according to Kyle Kondik, managing editor of Sabato’s Crystal Ball.

Pennsylvania's races, with polls closing at 8 p.m., offer similar insights. Democratic victories over Republican incumbents Ryan Mackenzie in PA-7 and Scott Perry in PA-10, both heavily blue-collar districts Trump won by five points or less, would indicate a solid Democratic performance. Republicans might grow more concerned if Democrat Paige Cognetti unseats first-term GOP Rep. Rob Bresnahan in PA-8, another blue-collar district in Northeast Pennsylvania that Trump won by over eight points.

PA-1 presents Democrats with their strongest opportunity to flip a House seat in Pennsylvania, attracting well-educated, upper-middle-class voters who have distanced themselves from the GOP under Trump. However, GOP Rep. Brian Fitzpatrick, first elected in 2016, has skillfully navigated a path of distancing from Trump without fully breaking ties. A win for Democrat Bob Harvie against Fitzpatrick would signify a historic wave, indicating a strong demand from white-collar voters disenchanted with Trump for more direct opposition to his agenda.

Geoffrey Skelley, chief elections analyst for Decision Desk HQ, commented, "This is the kind of stuff that happens in a wave. An incumbent has been strong; he’s been able to distinguish himself from his party enough to outperform (the district’s partisan lean). And then the environment gets bad enough and … suddenly it’s a lot harder to keep yourself separate from the party."

In Maine, polls also close at 8 p.m. A comfortable victory for Democrat Hannah Pingree in the Maine governor race would signal a solid night for the party. If progressive Democrat Matthew Dunlap defeats former GOP Gov. Paul LePage for the heavily blue-collar and rural ME-2 Congressional District, it would indicate an even better night for Democrats. The Maine Senate contest between Republican incumbent Susan Collins and Democrat Troy Jackson is a key race. Collins is the only Republican senator from the 19 states that voted against Trump in all three of his presidential elections. She was also the only Republican Senate incumbent or challenger during Trump’s first term to win in a state where exit polls showed more voters disapproved of his job performance.

Jackson has campaigned effectively since becoming the replacement candidate for Democrat Graham Platner. A Jackson victory would suggest Democrats are exceeding expectations, with the Trump disapproval rating (67% in the latest CNN Maine poll) potentially submerging even entrenched Republicans in swing or blue-tilting areas.

In New Jersey's NJ-7 House race, a win for Democrat Rebecca Bennett over Republican Rep. Tom Kean Jr., in a well-educated district narrowly carried by Trump, would indicate Democrats are on track for a good night. If Democrat Cait Conley defeats the more formidable opponent, GOP Rep. Mike Lawler, in NY-17, another white-collar seat narrowly carried by Trump, it would signal a stronger wave. A Democratic flip of NY-21, a predominantly working-class upstate New York seat vacated by Rep. Elise Stefanik, by Democrat Blake Gendebien, would signify historic wave levels.

The South

Early indicators from the South will come from Georgia, where polls close at 7 p.m. A solid reelection victory for Democratic Sen. Jon Ossoff, who has consistently led Republican Mike Collins in polls, would meet expectations. An upset win for Keisha Lance Bottoms over Republican Rick Jackson in the Georgia governor race, despite significant spending by Jackson, would indicate Democrats exceeding expectations.

North Carolina, with polls closing at 7:30 p.m., will also provide early markers. Former Democratic Gov. Roy Cooper is favored to flip the North Carolina Senate seat; a victory margin of at least 6 points would signal a good night for Democrats, according to Michael Bitzer, a professor of politics and history at Catawba College. Other signs of strong Democratic performance include Rep. Donald Davis holding the NC-1 seat, which Republicans redrew to favor Trump by over 11 points, and moderate Democrat Jamie Ager flipping NC-11, a district vacated by Republican Rep. Chuck Edwards and carried by Trump by about 10 points. Democratic capture of other GOP-held seats, such as NC-3 (Trump by 22 points) or NC-9 (held by NRCC Chair Richard Hudson), would signal historic breakthroughs.

In Florida, where the last polls close at 8 p.m., Democrats face baseline tests in holding seats redrawn by Republicans to favor the GOP. A win for Rep. Jared Moskowitz in FL-25 would signal a positive trend; reelection for Rep. Kathy Castor in FL-14 and Rep. Darren Soto in FL-9 would indicate a stronger current. Democratic victories in FL-13, held by Republican Anna Paulina Luna, or FL-7, a Republican open seat, would also signify a very good night. A win for Democratic nominee David Jolly, a former Republican, over Byron Donalds in the Florida governor race would be significant.

A historic storm for Democrats would involve ousting veteran GOP Rep. María Elvira Salazar in the heavily Hispanic FL-27, a seat Trump carried by 15 points, who has been more openly critical of Trump’s immigration policies than other Republican members of Congress. A Category 5 gale would occur if progressive Democrat Angie Nixon defeats Republican Ashley Moody in the Florida Senate race. Similarly, an upset win for Democrat Annie Andrews over Republican Sen. Darline Graham in the South Carolina Senate race (polls close at 7 p.m.) would mark a historic night, as Democrats haven't elected a senator there since 1998. A victory for Democrat Scott Colom over Republican Cindy Hyde-Smith in the Mississippi Senate race would be even more remarkable, with no Democratic senator elected there since 1982.

In Texas, where the last polls close at 9 p.m., Democrats haven't elected a US senator since 1988. A win for James Talarico over Ken Paxton, the scandal-plagued Republican nominee, despite significant Republican super PAC spending funded by Elon Musk and others, would indicate progress toward a very good night nationally. If Democrat Gina Hinojosa defeats Republican Greg Abbott in the Texas governor race, despite Abbott's substantial spending advantage, it would represent a historic breakthrough. Bill Miller, a leading lobbyist, described such victories, especially Hinojosa's, as "a generational win" for Texas Democrats.

Miller explained, "The key down here is that environment is good for Democrats and the money is good for Republicans, and how that washes out will be: Who gets their vote out? There are more Republicans than Democrats, and if Republicans do a better job, they will win a close election. If they don’t, they will lose a close election."

Texas House races will also provide insights, particularly regarding Trump's 2024 Latino support. Reelection wins for Democrats Henry Cuellar in TX-28 and Vicente Gonzalez in TX-34, in South Texas seats redrawn by Republicans, would meet expectations. If Tejano singing star Bobby Pulido defeats Republican Rep. Monica De La Cruz in TX-15 (a seat Trump won by 18 points) and/or sheriff’s deputy Johnny Garcia holds TX-35 (an open seat Trump carried by almost 11 points), it would indicate Democrats outperforming among Hispanics. An upset win for Democrat Katy Padilla Stout over Republican Brandon Herrera in the open TX-23 seat would signify a Democratic tide reaching tsunami levels.

The Midwest

The Midwest, which has shifted significantly towards Trump and the GOP in recent years, is now a central focus in American politics. Factors such as high gas and diesel prices, the disruptive impact of Trump's tariffs on the farm economy, and the president's weakening hold on the white working-class vote have fueled Democratic hopes for recovery in regions where they have seen declines.

As Skelley notes, these factors provide Democrats with reasons for optimism about a potential swing in the Midwest. Initial signals from the region will come from states with 7 p.m. poll closings. A Democratic capture of a Republican open seat in KY-6, a district Trump carried by 15 points, by Zach Dembo, or J.D. Ford's defeat of Republican Rep. Victoria Spartz in IN-5, where Trump won by nearly 17 points, would put the party on track for a very good night.

Ohio, with 7:30 p.m. poll closings, will offer the first comprehensive regional indicators. Following Republican redistricting, reelection victories for Democratic incumbents Greg Landsman in OH-1 and especially Marcy Kaptur in OH-9 would signal a solid Democratic path. A win for Democratic ironworker Brian Poindexter against Republican Rep. Max Miller in OH-7, a seat Trump carried by 11 points, would also be a positive sign.

Wins in key statewide races would represent bigger breakthroughs. A victory for Democratic former Sen. Sherrod Brown over GOP incumbent Jon Husted in the Ohio Senate race would indicate Democrats regaining some ground with white working-class voters lost during the Trump years. Although Democrats have not won an Ohio governor race since 2006, Amy Acton is considered a clear favorite over self-funding Republican Vivek Ramaswamy, particularly after backlash over his recent ad featuring her estranged mother. Ohio-based Democratic consultant Jeff Rusnak predicts, "As long as turnout (for Democrats) doesn’t collapse, Brown’s on track, and she’s on track." More surprising would be Democratic upsets in OH-10 or OH-15, held by GOP Reps. Mike Turner and Mike Carey, respectively, districts Trump won by eight and 10 points.

The next significant Midwestern signals will come from states with 9 p.m. poll closings. In Iowa, Democratic victories over Republicans Mariannette Miller-Meeks in IA-1 and Zach Nunn in IA-3, seats Trump won by eight and four points respectively, would align with expectations. A win for Democrat Rob Sand in the Iowa governor race, who has led in polls all year despite Democrats not electing a governor there since 2006, would also meet expectations. An upset win for Democrats in IA-2, a more reliably Republican seat vacated by Ashley Hinson, the party’s Senate nominee, would signify a larger wave. A win for Democrat Josh Turek over Hinson in the heated Iowa Senate race would also be significant; similar to Brown in Ohio, a Turek win would depend on Democrats recovering support among working-class Whites, particularly in rural areas impacted by Trump’s tariffs and rising diesel costs.

Wisconsin presents a similar scenario. A win for Democrat Rebecca Cooke over Republican Derrick Van Orden in the WI-3 House race would signal a good night. Victories for Democrat Mitchell Berman over Republican Bryan Steil in WI-1, and for Democrat David Crowley in the open Wisconsin governor race, would indicate more significant gains.

In Michigan, a comfortable win for Democrat Jocelyn Benson in the Michigan governor race is the baseline for a good Democratic night. Flipping Republican-held House seats in MI-4 and MI-7 would also keep Democrats on track. MI-7 is more favorable, but its nominee, William Lawrence, is considered weaker than state Sen. Sean McCann in MI-4, according to David Wasserman, senior elections analyst for the Cook Political Report with Amy Walter.

Regardless of these outcomes, the Michigan Senate race remains pivotal. Democrat Abdul El-Sayed and former Republican Rep. Mike Rogers are in a close contest, recently dominated by Islamophobic remarks from Trump and other Republicans portraying El-Sayed, who is Muslim, as a "jihadist." Before this, an El-Sayed win might have been considered holding serve. However, if El-Sayed prevails amid conspicuous defections by some Jewish Democrats, it would further indicate that the Trump undertow (his disapproval reached 66% in a new CNN Michigan poll) is too strong for Republicans to overcome.

This message would be amplified if Republican Roger Marshall beats Democrat Adam Hamilton in the Kansas Senate race (the state hasn't elected a Democratic senator since 1932); if independent Dan Osborn topples Republican Pete Ricketts in the Nebraska Senate race; or if independent Brian Bengs upsets GOP Sen. Mike Rounds in the South Dakota Senate contest. Democratic wins in any of these races would propel the night into "tsunami territory."

The West

Colorado and Arizona, with 9 p.m. Eastern poll closings, offer a clear progression of opportunities for Democrats. A win in the CO-8 House race, where Republican Gabe Evans faces former state Rep. Manny Rutinel in a district north of Denver that Trump carried by less than two points, would align with a good Democratic performance. A victory for Democratic Army veteran Jessica Killen over Republican Jeff Crank in CO-5, a district Trump won by nine points, would signify a very good night. If Democrats unseat Republican Reps. Jeff Hurd in CO-3 or Lauren Boebert in CO-4, the latter a seat Trump won by more than 18 points, the "flood" would be mountain-high.

In Arizona, a comfortable reelection for Democrat Katie Hobbs over hard-line Republican Andy Biggs is considered the minimum for a good Democratic night. Success in flipping AZ-1, a well-educated and affluent seat in the northeast Phoenix suburbs vacated by Republican Rep. David Schweikert, would also be significant. Trump has actively promoted the GOP nominee, Jay Feely, a former NFL kicker and golfing partner of the president, but Feely is now the underdog against Democrat Amish Shah. More impressive would be if Democratic Marine veteran JoAnna Mendoza defeats Republican Rep. Juan Ciscomani, who has positioned himself as a moderate, in AZ-6, a seat centered on Tucson suburbs that Trump carried by less than a point.

In Alaska, where the last polls close at 1 a.m., Democratic former state Rep. Jonathan Kreiss-Tomkins is a strong favorite in the Alaska governor race, even receiving an endorsement from Republican Sen. Lisa Murkowski. A win would indicate Democrats are on a solid path in the state.

A more significant victory would be in the Alaska Senate race for Democrat Mary Peltola, a former US representative, over Republican Sen. Dan S. Sullivan. Sullivan has emphasized his role in promoting oil and gas development, which is popular in Alaska. Alaska has elected only four Democratic senators since 1959, and just one since 1980. Peltola, who could be the first Alaska Native elected to the Senate, has focused on "Fish, Family, and Freedom" and benefited from discontent over soaring gas and diesel costs.

The Trump administration has preemptively sued to invalidate the results if Peltola wins, citing a candidate named Dan J. Sullivan on the ballot. However, most legal observers consider this litigation unlikely to succeed. The New York Times reported that Democrats aligned with Peltola's campaign worked to recruit the other Dan Sullivan, prompting investigations from Alaska's Republican governor and the Justice Department. While this controversy could impact Peltola electorally, legal experts believe it is unlikely to provide a basis for rejecting the outcome.

Elsewhere in the West, a win for progressive Randy Villegas over Republican David Valadao in CA-22, a swing and heavily Hispanic district in California's Central Valley, would be a positive result for Democrats. A reelection for center-right Democratic Rep. Marie Gluesenkamp Perez in WA-3, a Southwest Washington seat Trump carried by three points, represents a similar level of difficulty.

Polls close at 11 p.m. in California and Washington. If Democratic Gov. Tina Kotek holds off Republican Christine Drazan in the Oregon governor race (polls also close at 11 p.m.) despite low approval ratings and discontent over the economy and homelessness, it would signal an insurmountable backlash against Trump for blue-state Republicans. An upset for Democratic Attorney General Aaron Ford over Republican Joe Lombardo in the Nevada governor race (polls close at 10 p.m.) would also mark a stronger Democratic current. A win for Democratic smoke jumper Sam Forstag in MT-1, a seat Trump carried by nearly 12 points, would be notable.

Democratic wins in two other House districts would signify an historic tide. One is AZ-2, a seat Trump won by 15 points, where Republican Rep. Eli Crane faces former Navajo Nation President Jonathan Nez. The other is NV-2, an open seat in northern Nevada that gave Trump a 14-point margin. A surge in turnout from die-hard Trump supporters, which pollsters may have missed, could still temper Democratic gains. However, a good night for Republicans might simply be one that avoids historically bad results.
