Democrats are heading into the final stretch of the 2026 midterm campaign with strong momentum, analysts said, as President Donald Trump's unpopularity expands the electoral map into traditionally Republican territory. The party needs to flip just three seats to take control of the House, and projections suggest they will easily surpass that threshold.
“It’s still not clear exactly how deep into the map Democrats can play,” said Erin Covey, the top House analyst at the Cook Political Report with Amy Walter, during a Brookings Institution panel. “But regardless of how far they can expand the map, I think they are going to be in a very good position to win the House, and the Senate perhaps as well.”
Trump's approval rating has sunk to 31%, according to a Reuters/Ipsos poll released Monday. His handling of the economy, in particular, polls in the 20s, said William Galston, a senior fellow at Brookings and a former official in the Clinton White House. Galston pointed to the administration's failure to rein in inflation and its involvement in a new Middle East war as broken promises that have eroded support.
“Other than core MAGA supporters, it is very difficult to find any appreciable pool of voters who think that the president has done a good job managing inflation, high prices, affordability,” Galston said.
Democrats have also gained ground on immigration, an issue that once favored Trump. Galston said an aggressive interior enforcement crackdown that led to shooting deaths of U.S. citizens by federal agents had turned immigration into “a jump ball.”
Still, even the upper end of projected House gains – 20 seats – would be far smaller than the 41 seats Democrats won in the 2018 midterms or the 63 seats Republicans gained in 2010. Covey attributed this to Democrats entering the cycle with a “higher floor” of 214 seats, leaving less room to expand, and to fewer competitive districts after redistricting.
Mid-decade redistricting by Republican-led states, beginning with Texas in August 2025, was expected to net the GOP eight to 10 seats in a neutral year. But Covey said that in the current environment, the GOP may gain only about three seats from the redrawn maps, and possibly none at all.
“That environment will shift in the next two election cycles, while the district lines are less likely to move,” said Christopher Warshaw, a Georgetown University public policy professor. “In 2028 or 2030, I think the mid-decade redistrictings will have a much more important impact.”
The Senate race remains closer to a toss-up, with experts estimating Democratic gains of two to six seats. A net gain of four would flip that chamber as well. However, outside spending by Republican super PACs has heavily favored GOP Senate candidates, a sign that Republicans may be conceding the House while trying to shore up their Senate majority, Covey said.
