What

Republicans hold slim majorities in both the House and Senate with a Republican president, setting the stage for the 2026 midterm elections where Democrats aim to reclaim control of both chambers.

Who

The Democratic Party is seeking to flip three House seats and four Senate seats to achieve a majority, while the Republican Party is defending its narrow control against historical midterm trends favoring the opposition.

Context

Historically, the party not in the White House has gained House seats in all but four midterm elections since the Civil War, giving Democrats a structural advantage in this cycle.

CNN

Stakes

A Democratic sweep would block President Trump's legislative agenda, enable investigations into his administration, and shift the national policy trajectory toward Democratic priorities.

The Guardian

Note: Decision Desk HQ's latest forecast estimates a 40% chance Democrats win full control of Capitol Hill, while acknowledging the Senate is on track for a 50-50 split.

Washington Post
