A new high for political independence
For the first time in the history of Gallup’s tracking, the share of Americans who refuse to identify with either major party has broken new ground. A record-high 45% of US adults identified as political independents in 2025, surpassing the previous high of 43% reached in 2014, 2023, and 2024, while equal shares of 27% identified as Democrats or as Republicans. Gallup called it the highest level recorded in its three decades of tracking American voter affiliation. In most years since Gallup began its regular telephone polling in 1988, independents have actually been the largest single group, but the share has climbed markedly over just the past fifteen years.
Younger generations are driving the shift
The generational pattern behind this trend is striking. Gallup found that 56% of Generation Z and a majority of Millennials now identify as independents, compared with far smaller shares among older generations such as the Silent Generation. Unlike previous generations, Gen X and Millennials appear to be bucking the historical pattern of returning to a major party as they age, remaining independent well into adulthood. Gallup noted that Generation Z is following the same disproportionate independent identification seen among young people in earlier eras, suggesting the trend could persist as this cohort grows older.
The parties’ brand problem
Part of what is pushing voters away from party labels appears to be dissatisfaction with the parties themselves, rather than any single issue. A separate Gallup finding showed that larger majorities than in 2011 — 69% regarding Republicans and 60% regarding Democrats — now say both parties go too far in using inflammatory language to criticize their opponents. That kind of shared exhaustion with partisan rhetoric, cutting across the political spectrum, helps explain why independence has grown even among voters who don’t necessarily agree with each other on policy.
A shift in which party benefits
Independent voters aren’t a monolithic bloc, and their leanings have moved substantially in a short period. The political landscape shifted considerably in the first year of Trump’s second term, as a record share of Americans distanced themselves from both parties and a change in independents’ leanings erased the Republican advantage that had aided Trump’s re-election almost as soon as he took office. Gallup’s data showed Democratic-leaning independents rising from 17% in 2024 to 20% in 2025, while Republican-leaning independents fell from 18% to 15% over the same period. Analysts attribute this dynamic less to newfound enthusiasm for either party than to dissatisfaction with an unpopular incumbent president — first Biden, and now Trump — a pattern that has repeatedly cost the president’s party control of Congress or the White House in each of the last six election cycles.
Why voters say they’re leaving the parties behind
Beyond the polling numbers, individual voters describe a similar frustration in their own words. One Louisiana voter told ABC News that growing political divisiveness has made it feel as though a vocal minority on both sides speaks for the majority, leading him to identify as independent even though he stays registered as a Republican specifically so he can still vote in Republican primaries. Former Biden administration press secretary Karine Jean-Pierre, who became an independent herself, argued that the trend is not temporary and will continue to reshape the American electorate.
The primary problem
The mechanics of the American electoral system complicate the picture in an important way. Many states hold closed primaries, meaning only voters registered with a specific party can help choose that party’s nominee, which pushes some independent-minded voters to maintain a formal party registration purely as a strategic move. This creates a structural disconnect: primary electorates skew more partisan than the general electorate, even as a growing share of that general electorate rejects party labels altogether — a mismatch that critics argue helps produce nominees who don’t reflect the broader public’s preferences.
States are already adapting
Some states are experimenting with rules explicitly designed to give independents more influence. California’s “top two” open primary system allows candidates to advance to the general election ballot simply by finishing among the top two vote-getters regardless of party, which forces campaigns to build coalitions that cut across traditional partisan lines. The state’s shift is visible in registration data too, with no-party-preference voters now nearly matching registered Republicans statewide. In Colorado, registered independents surpassed 50% of the voting population in 2025, a threshold few states have crossed.
The stakes for the 2026 midterms
With midterm primaries already underway in several states, the independent surge is becoming difficult for either party to ignore. Unlike in past cycles, when media coverage of independent voters’ influence often arrived only after primaries had concluded, the sheer size of this bloc — now approaching half the electorate — is forcing earlier attention in the 2026 cycle. One political strategist told ABC News that parties failing to move toward the center risk pushing independents to cross the aisle entirely, even toward candidates they don’t fully agree with, simply because that candidate seems willing to listen.
A structural, not cyclical, shift
Taken together, the data suggests this is not a temporary protest vote but a longer-term restructuring of how Americans relate to the two-party system. Independent identification has typically registered at 40% or higher for the past fifteen years, a level that was never reached before 2011 — meaning today’s numbers represent the continuation of a trend more than a sudden reaction to any single election cycle. Whether that trend eventually forces structural changes to how primaries and elections are run, or simply leaves both major parties chasing an ever-larger bloc of persuadable voters, is likely to be one of the defining storylines of American politics through the rest of the decade.
