Gallup said Democrats held a wider edge over Republicans in the second quarter of 2026, with 31 percent of U.S. adults identifying as Democrats and 25 percent identifying as Republicans. That six-point gap was the largest Democratic lead in party identification in more than a decade.
The timing matters because the numbers arrive just before the November midterms, when control of the House and Senate is on the line. Gallup also found that 49 percent of respondents identified as Democrats or leaned Democratic, compared with 39 percent who identified as or leaned Republican, a 10-point gap and the largest since 2008.
That shift is sharper than it looked a year earlier, when 46 percent identified or leaned Democratic and 43 percent identified or leaned Republican. The last time Republicans held the advantage in the broader measure was the fourth quarter of 2024, when they led by 4 points, a period that coincided with Trump’s presidential election.
Jeffrey Jones said party identification tends to move with the political mood. “When things are going well in the country, party identification shifts in the direction of the party in charge,” he said. “When things are going poorly, like they are now with an unpopular Republican president and people unhappy with the state of the nation, people are moving away from the party in charge.”
He compared the pattern with the closing months of the George W. Bush administration, when he said Republicans were in a similar position before the 2006 and 2008 elections. That is the part Republicans cannot ignore: they face a bigger Democratic registration and leaners advantage even as Trump plans to campaign nationwide for them and has told supporters, “Pretend I’m on the ballot.”
Party identification does not move in a straight line, and it does not decide a congressional election by itself. But the direction is clear enough to matter. Republicans usually lose seats in midterm elections, and the current Gallup numbers suggest they are heading into this one with less room to recover than they had at the end of 2024.
The real test is whether that partisan shift turns into votes in November. If it does, the balance in Congress could move before Trump’s campaign travel ever has a chance to do much about it.
