Democrats Aim to Retake Senate as Voters Head to Polls 2026

Democrats aim to retake the Senate from Republicans as Americans go to the polls in the midterm elections, hoping to flip at least four seats and regain control of Congress' upper chamber. The party lost its majority in 2024 when voters re-elected Donald Trump and gave Republicans 53 seats.

The first race results have begun trickling in, with the Associated Press calling the Virginia Senate election for Democratic incumbent Mark Warner, who was expected to win. Polls opened across all 50 states and Washington DC after millions voted early or by mail.

Why the Senate Majority Matters

Control of the Senate would give Democrats a potent tool against Trump for the final two years of his presidency. They could block the president's bills and issue subpoenas to investigate his administration. They could also reject his nominees to the federal judiciary, including the Supreme Court.

At the outset of Trump's presidency, it seemed unlikely Democrats had a shot at regaining control. Most senators up for re-election represented solidly red or blue states, giving Democrats few offensive opportunities. But Trump's approval ratings have shifted the landscape.

Key Races to Watch

Democrats need a net gain of four seats to reach 51 and take control. Several Republican-held seats in competitive states are in play, while Democrats must defend their own incumbents in tougher-than-expected districts.

The Virginia result is an early sign of Democratic enthusiasm, but it was expected. The real bellwethers will be in states where Trump's approval has dipped and where suburban voters are shifting.

• Four-seat swing: Democrats must flip at least four Republican seats to win the majority.
• Virginia called: Incumbent Mark Warner (D) has won re-election, per the AP.
• Judicial stakes: A Democratic Senate could block Trump's court nominees, including any Supreme Court picks.
• Subpoena power: Democrats could launch investigations into the administration.
• Legislative check: A Democratic Senate could halt Trump's legislative agenda.

What the Polls Show

Trump's approval ratings have fallen below 50% in several key states, according to recent surveys. That has given Democrats hope in traditionally Republican-leaning areas.

Democrats believe voters' dissatisfaction with Trump will put them back in control of Congress' upper chamber just two years after being driven into the minority. The party is banking on energy from early voters and a focus on kitchen-table issues.

Impact on Trump's Agenda

If Democrats win the Senate, Trump's ability to pass legislation would be severely curtailed. He would need to rely on executive actions, which are more vulnerable to legal challenges.

Additionally, a Democratic Senate would likely block many of his judicial nominees, reshaping the federal judiciary's ideological balance. This could have long-lasting effects beyond Trump's presidency.

What to Watch Next

As results come in from key states, the path to a Democratic majority will become clearer. The party needs to hold all its seats and flip four Republican ones. Early turnout and suburban margins will be critical indicators.

The midterms are also a test of Trump's coattails: if his approval remains low, Republicans in swing states could suffer. Conversely, a late surge could preserve the GOP majority.

Investors and business leaders are watching closely, as a divided government could lead to gridlock on tax and spending bills. Markets often prefer stability, but a Democratic Senate could push for higher taxes on corporations.
