Midterm elections are held every two years in the United States, occurring exactly halfway through a presidential term. Because the entire House of Representatives and one-third of the Senate are up for election, these contests act as a national referendum on the sitting president's performance. The outcome of these elections is significant because it dictates whether the president's party maintains control of Congress or if the opposition party gains the power to block or advance the administration's policy agenda.

Historically, the party in power often faces political headwinds during midterms, as voters use the opportunity to express approval or dissatisfaction with the current executive branch. In the context of the Trump administration, the stakes were framed as a test of the Republican party's legislative influence. While the president's term remains unaffected by the results, the political landscape shifts significantly based on which party holds the majority in the House and Senate. Democrats have historically viewed these elections as a primary mechanism to check executive power, while the administration often frames the vote as a direct endorsement of its own leadership, even when the president is not personally on the ballot.
