US Midterms Elections 2026: What Democrats Can and Can’t Do After Winning Congress

Democrats have flipped both the House and the Senate in the 2026 midterms. The result is a sharp rebuke of Republicans and President Donald Trump’s agenda. Hakeem Jeffries is now in line to become speaker when the new Congress convenes in January. Chuck Schumer is set to return as Senate majority leader. The final two years of Trump’s term will look very different from the first two.

However, victory does not give the party a free reign in Washington. Trump still holds the veto power, and Republicans can still slow most bills in the Senate. Democrats have promised action on living costs, healthcare and the war in Iran. They have also pledged to investigate what they describe as corruption inside the government. The gap between what they can start and what they can finish will shape the next two years.

Subpoenas, Confirmations and Impeachment: The Powers Democrats Now Hold

The quickest tool Democrats have is oversight. Committees in both chambers can summon officials, order subpoenas, demand documents and hold public hearings. Robert Garcia, the expected chair of the House Oversight Committee, told Republicans on election night to lawyer up. Likely targets include Trump family business dealings, immigration enforcement, the Pentagon and Iran war and the Epstein files and emails. However, the administration could resist those demands, escalatiing several fights to court.

The Senate majority gives Democrats control over confirmations. They can block or delay cabinet picks, ambassadors and judges, including any Supreme Court nominee. The House can also impeach a president with a simple majority vote. Jeffries has said nothing is ruled in or out, while Republicans predict a push on day one. Conviction, however, needs 67 Senate votes, which remains far out of reach.

Veto Threats, the 60-Vote Rule and Party Splits Could Limit the Agenda

Passing laws will be far harder than launching investigations. Democrats can now bring bills to a vote in the House. Most legislation, however, needs 60 votes in the Senate to avoid procedural blockage. Overriding a presidential veto requires two-thirds of both chambers, a margin Democrats do not have. Trump has accepted the Republican defeat, yet he also posted a picture of a hat reading veto. Democrats plan to start with affordability. Jeffries has promised to restore expired Affordable Care Act subsidies and reverse nearly $1 trillion in Medicaid cuts. Those goals may face a veto, so many proposals could serve as messaging ahead of 2028.

Divisions inside the party add another hurdle, particularly over Medicare for All, AI regulation and aid to Israel. Congress has also struggled to enforce limits on the Iran war, since Trump has ignored a June resolution. Ultimately, the 2026 midterms hand Democrats real leverage but not unchecked power. Oversight, confirmations and spending fights give them tools to test the administration right away. Lawmaking, however, will depend on whether they can stay united and win some Republican support. Voters have shown frustration with Washington, and an October poll put congressional approval at 14 percent. How Democrats balance scrutiny with results may shape the 2028 presidential race.
