Democratic party gets largest advantage over Republicans since 2008, survey shows
Independent voters are increasingly leaning toward the Democratic Party ahead of November’s United States midterm elections, according to Gallup’s latest quarterly party affiliation data reported Saturday by the Washington Examiner.
Among respondents in Gallup’s second-quarter survey who identified as neither Republicans nor Democrats, 49% said they leaned toward the Democratic Party, compared with 39% who leaned Republican.
The Democratic advantage among independent voters has grown by four percentage points since the first quarter of 2025, when President Donald Trump returned to the White House for his second term.
The shift is also reflected among voters who identify directly with a political party.
