A national poll released Wednesday shows Democrats expanding their advantage among white voters in the race for control of the House of Representatives, a sign that economic frustration and foreign policy preoccupation have begun to erode Republican support even within their core demographic.
According to Big Data Poll, Democrats now lead Republicans on the generic ballot by 13 points overall—their largest advantage ever measured—driven partly by declining white voter support for the GOP.
The poll, conducted April 25-28 among 3,176 registered voters, found Democrats leading 50.4 percent to 39.4 percent among likely voters. Among white voters, Democrats captured 41.5 percent compared to 41.1 percent for Republicans, with 5.8 percent choosing third-party candidates and 11.6 percent undecided.
Big Data Poll Director Rich Baris said in a statement that “voters have clearly run out of patience with the administration and [the Republican] party,” describing the Democratic advantage as driven by “voter enthusiasm, more interest in voting on behalf of Democrats, crossover voting and independent preference both favoring Democrats, and deep frustration with Republicans over their failure to enact domestic policies.”
The poll captures a moment of significant weakness for Republicans. President Donald Trump’s job approval rating stands at 39.6 percent, a new low in his second term and approaching the critical 30s, according to Baris. Meanwhile, 56.9 percent disapprove, including 45.2 percent who strongly disapprove.
Republicans’ struggle with white voters represents a dramatic compression from recent elections. The party has dominated this demographic for decades, but margins have tightened substantially as independent and crossover voting accelerates.
White voters remain the largest single bloc in American elections. In 2024, they made up roughly 71 percent of those who voted nationally. But their loyalty to the Republican Party has fractured along education lines and shifted on key issues—particularly foreign policy, where an unpopular war in Iran is taking a visible toll.
Voters overwhelmingly blame Republicans for what they see as administration overreach on foreign engagement. Sixty-two percent say the White House is too focused on foreign policy versus domestic issues—up from 56.3 percent in January—while just 13 percent say it is too focused on domestic matters.
The direction-of-country question shows even sharper deterioration. About 32 percent of voters say the country is headed in the right direction—the lowest reading since January 2025—while 59 percent say it is on the wrong track, up from 58.3 percent in March. The 27-plus-point spread is the widest negative margin in Trump’s second term.
The Big Data Poll results align with recent developments in 2026 chamber-control forecasts. According to Race to the WH, Democrats’ odds of winning House control have climbed to 78.2 percent following Virginia’s midcycle redistricting and strong fundraising. Democrats need to flip just three seats to secure a House majority.
Senate control remains closer, according to prediction markets. Polymarket shows Democrats holding a 52 percent implied probability of controlling the chamber, while Kalshi gives Republicans the edge at 52 percent.
Democrats’ Recent Performance with White Voters
The Democratic position with white voters, while still trailing, marks a notable shift from the party’s recent electoral history.
In 2016, Hillary Clinton captured just 37 percent of white voters nationally while Trump took 57 percent—a 20-point Republican advantage. Four years later, Joe Biden improved to 41 percent among white voters, narrowing the gap to 17 points. The improvement came almost entirely from college-educated white voters, particularly women, who shifted significantly toward Democrats. Biden won college-educated white women by 9 points in 2020, an 18-point swing from Clinton’s 2016 showing.
In 2024, Trump’s overall margin with white voters remained essentially flat, but the makeup of the electorate shifted as white voters declined from 73 percent of those who voted in 2020 to 71 percent. Among the white voters who did cast ballots, Trump won 56 percent to Harris’ 44 percent nationally.
The April 2026 generic ballot parity among white voters—with Democrats at 41.5 percent and Republicans at 41.1 percent—represents uncharted territory for either party testing with this demographic. Even more striking: When third-party preferences are removed and voters are forced to choose, Democratic support among whites reaches 46.8 percent while Republican support falls to 46.5 percent.
Baris cautioned that Democrats’ lead does not reflect broad enthusiasm for their party.
“Democrats are simply the alternative to the party in power voters understandably blame for their current situation,” he said.
On issues in which Republicans historically held an advantage, the poll shows compression. On immigration and border security, Democrats trail 40.8 percent to 38.0 percent—essentially tied when margin of error is factored in. That represents a shrinkage of Republicans’ traditional edge on the issue.
Trust in handling the economy tilts Democratic, 43.4 percent to 35.2 percent. On inflation and cost of living—typically a Republican strength—Democrats hold a 43.5-34.0 edge. The shift suggests that economic messaging from the Trump administration has failed to gain traction with voters concerned about their household finances.
