A Blue Wave Is Taking Shape. The Senate Will Test Its Strength.

American presidents often discover that winning the White House is easier than protecting their party from the electorate two years later. Midterm elections give voters an opportunity to reconsider the governing party’s promises, register disappointment and impose a measure of restraint. As November 3 approaches, Republicans face the possibility that this familiar correction could become a substantial repudiation.

The historical pattern is striking. Since 1938, the president’s party has lost House seats in every midterm election except 1998 and 2002. Some losses have been devastating: Democrats surrendered 63 seats during Barack Obama’s first midterm in 2010, while Republicans lost 41 during Donald Trump’s first presidency in 2018. Even the comparatively modest Democratic loss of nine seats in 2022 was enough to end the party’s House majority. Losing seats and losing control are different outcomes, but a narrow majority makes the distinction painfully small.

The exceptions also offer a lesson. Bill Clinton entered the 1998 election with strong public approval despite the scandal and impeachment proceedings surrounding his presidency; the House impeached him after the election. George W. Bush benefited in 2002 from the national solidarity that followed September 11. In both cases, the president’s party gained House seats under circumstances that helped overcome the usual midterm disadvantage.

Trump enters this election in a considerably weaker position. An ABC News-Washington Post-Ipsos poll released October 18 put his approval rating at 33 percent, the lowest recorded for him in that survey series across either presidency. The same poll found Democrats leading Republicans among likely voters on the congressional ballot by eight percentage points, 52 percent to 44 percent.

Those numbers constitute a serious warning for Republicans. They do not, however, provide a mechanical formula for translating presidential unpopularity into congressional losses. District boundaries, candidate quality, campaign resources and turnout still determine how national dissatisfaction becomes actual seats.

Nevertheless, the electoral map is moving. On October 16, the Cook Political Report shifted another 11 House races toward Democrats. Such changes indicate that Republican vulnerability is extending beyond the most obvious battlegrounds. They strengthen the case for a Democratic House takeover, although they cannot establish its eventual size.

The Senate presents a more demanding test. Republicans hold a 53–47 advantage, counting the two independents who caucus with Democrats. With 35 seats on the ballot, Democrats need a net gain of four to secure an outright majority. That requires defending their own vulnerable seats while winning several Republican-held contests. Michigan and Georgia, both carried by Trump in 2024, remain essential defensive obligations. A favorable national environment makes that task more plausible; it does not make it easy.

The emerging opportunities nevertheless deserve attention. In my home state of North Carolina, former Democratic governor Roy Cooper has made the open Senate seat a particularly promising opportunity for his party. Republican Senator Thom Tillis announced his retirement after a confrontation with Trump over legislation containing Medicaid cuts. Cooper’s established statewide profile has helped him build a substantial polling advantage over Republican Michael Whatley: Elon University’s final pre-election survey reported a 13-point lead among likely voters.

North Carolina illustrates why national conditions and local credibility must be considered together. Cooper has already demonstrated his ability to win statewide in a closely divided electorate. His candidacy gives Democrats an opening grounded in an established political record.

Maine, where I attended college, offers a different contest. Senator Susan Collins has survived difficult elections before, and her longstanding reputation for independence makes predictions of her defeat hazardous. Yet Democrat Troy Jackson has a credible opportunity. A Rasmussen survey conducted October 5-8 placed him ahead, 49 percent to 47 percent, within the survey’s margin of sampling error. The appropriate conclusion is that Maine is competitive, with a narrow polling advantage for Jackson.

Ohio adds another consequential possibility. Former senator Sherrod Brown, defeated in 2024, is challenging Jon Husted in the special election for the seat vacated by Vice President JD Vance. Brown’s long political career makes him a familiar figure in a state that has moved toward Republicans. Several polling averages show him ahead, although an October ActiVote survey gave Husted a fractional lead. That variation matters: Ohio represents a plausible Democratic pickup, with enough uncertainty to resist confident declarations.

In Alaska, former representative Mary Peltola is mounting a serious challenge to Senator Dan Sullivan. Her previous statewide success and distinctive political profile complicate assumptions about an otherwise Republican-leaning state. Reporting on the race points to affordability concerns as a central vulnerability for Sullivan. Prediction-market odds may reflect changing expectations, but they should not substitute for evidence about voters.

Even Texas is generating credible evidence of competition. A University of Houston Hobby School poll reported Democrat James Talarico narrowly ahead of Republican Ken Paxton, 48 percent to 46 percent. One close poll cannot establish an impending political realignment, but it helps explain why Democrats see opportunities beyond their traditional battlegrounds.

Taken together, these races make Democratic Senate control a serious possibility. A 52- or 53-seat Democratic caucus would require a broader collection of victories and should be treated as an optimistic scenario rather than an established forecast. Small, correlated polling errors could still change several outcomes at once.

There is also a story here about political participation that extends beyond congressional arithmetic.

For Bangladeshi Americans, New York City’s recent mayoral election challenged familiar assumptions about the community’s electoral engagement. Reporting documented the work of immigrant women organizing their neighbors and the strength of participation in Bangladeshi neighborhoods. Their experience offers a reason to reconsider sweeping descriptions of immigrant communities as politically disengaged. Participation is shaped by whether people feel recognized, whether their concerns receive attention and whether meaningful opportunities to engage exist.

That lesson has relevance across the electorate. Voters who rarely appear in national political commentary can become consequential participants in local and statewide contests. Their choices deserve examination without assuming that ethnicity, religion or immigration history determines political allegiance.

The evidence now supports a strong argument that Republicans face a difficult election and that Democrats have a credible path to controlling both chambers. History, presidential approval and the expanding competitive map all point in that direction.

But an electorate capable of punishing overconfidence in government can also punish overconfidence in opposition. Democrats have an opportunity. Whether it becomes a blue wave will depend on the decisions voters make, race by race, before the final ballot is counted.
