If Democrats gain control of Congress, they would gain power to block Trump's agenda, investigate his administration, and advance their own priorities on healthcare, the economy, immigration enforcement, and other issues. However, they would face significant constraints from the Senate filibuster, Trump's veto power, and White House tactics.
Democratic leaders say they plan to quickly pass bills on healthcare, tariffs, and Iran policy if they win the majority. But most such bills would need 60 Senate votes to advance under current rules, requiring significant Republican support, or Trump could veto them anyway.
Democrats pursuing legislative wins under Trump would likely rely on three approaches. First, they could attach demands to "must-pass" bills like government funding or debt ceiling increases. Bobby Kogan, senior director of federal budget policy at the Center for American Progress, said Democrats are historically reluctant to use the debt ceiling as leverage, viewing the risk of default as too catastrophic. Democrats are more likely to make demands tied to government funding, which they have done before. Last year, even while in the Senate minority, Democrats used the filibuster to shut down the government, demanding Republicans extend Affordable Care Act subsidies. Some experts are skeptical Democrats will successfully pressure Trump into concessions this way. During last year's shutdown, enough Democrats eventually gave in as consequences mounted for unpaid workers and benefit recipients.
Second, Democrats could seek bipartisan support. Bipartisan bills on Covid relief, infrastructure, semiconductors, same-sex marriage, and election reform have passed in recent years. Matthew Fiedler, a senior fellow at the Brookings Institution, said Democrats could add riders to appropriations bills blocking controversial Trump regulatory actions, though they would need Republican consent to get bills to Trump's desk. A bipartisan housing bill passed this year without Trump's signature.
Third, Democrats could generate political pressure around popular proposals that Republicans feel compelled to support. Rep. Ro Khanna's bill to release the Epstein files passed with overwhelming majorities last year after GOP leaders tried to block it.
On oversight and investigation, Democrats would gain access to subpoena power if they control either chamber, allowing them to investigate Trump's administration and bring wrongdoing to light. If they control the Senate, they would also gain power over the confirmation process for Trump's nominees.
Congressional aides and outside experts told the reporter they expect frustration and disappointment, as the Democratic base's expectations may exceed what can realistically be achieved. Some expressed cautious optimism that Democrats could score meaningful accomplishments if they use their tools strategically.
