With exactly one month until Election Day, Republicans are confronting what appears to be an increasingly precarious political map, as polling and election forecasters show Democratic candidates competitive or ahead in several races that could determine control of both chambers of Congress. Democrats are hoping polling surges and low approval ratings for President Donald Trump help them ride a massive blue wave into the majority in both the House and the Senate. Republicans hope the president hitting the campaign trail can boost turnout among their base and stave off Democratic gains.
Voters head to the polls on November 3, with every House seat and 35 Senate contests on the ballot. Democrats need to pick up four seats each in both the House and the Senate to gain control of the chambers. Political forecasters like Cook Political Report and Sabato's Crystal Ball have shifted numerous races toward Democrats, and though many contests remain within tight and within polling margins of error, the emerging picture raises the prospect of substantial Republican losses.
The generic ballot—which assesses how a typical politician would fare in a race based just on party—puts Democrats ahead by over eight points, according to RealClearPolitics' polling average. In the 2018 midterms during Trump's first term in office, Democrats rode a blue wave to a net gain of 41 seats in the House, but they were not able to sustain that momentum against a difficult Senate map, ultimately seeing the GOP expand its majority from 51 seats to 53. The map appeared similar in 2026, with only two Republican seats being defended in states that Democratic nominee Kamala Harris won in 2024, but the battleground has expanded to longtime GOP strongholds amid voters' dissatisfaction with the economy, inflation and the Iran war. https://public.flourish.studio/visualisation/30414104/ A polling snapshot from Election Central, updated September 28, showed Democrats leading in six Republican-held Senate contests—Alaska, Iowa, Maine, North Carolina, Ohio and Texas.
And four major election forecasters—FiftyPlusOne, Silver Bulletin, Split Ticket, and VoteHub—predict that all five of those races (taking out Iowa) favor Democrats. Despite the GOP currently holding North Carolina, former Democratic Governor Roy Cooper has taken such a commanding lead over his opponent, former Republican National Committee Chairman Michael Whatley, that NBC reports that the GOP's top Senate super PAC has paused spending in the race. If each party won every other seat they are expected to hold, victories in those six races would put Democrats above the four-seat gain needed for Senate control.
These figures are a snapshot, however, and not a forecast. Several of the margins were narrow. Newsweek contacted the National Republican Senatorial Committee for comment on the midterms and was directed to reporting by CNN noting that polling of MAGA Republicans indicates high enthusiasm for the election.
Additionally, the NRSC pointed to analysis by conservative pollster Patrick Ruffini showing that Senate polling from 2018–2024 overstated Democratic turnout in Iowa, Ohio, and Michigan “Democrats should think twice before relying too heavily on the same rosy polling that has historically written Republicans off cycle after cycle," NRSC National press secretary Bernadette Breslin said in prior statements. In Alaska, former Democratic Congresswoman Mary Peltola has raised over $18.5 million in her challenge against incumbent Senator Dan Sullivan. Currently, the RealClearPolitics' polling average gives her a one-and-a-half-point lead over Sullivan.
