Midterm Elections

Every two years, halfway through a president's term, the country holds an election with no presidential race at the top: the whole U.S. House, about a third of the Senate, most of the nation's governors, and thousands of state and local offices. Here is what a midterm is, what it can and cannot change, and why its results so often break against the party in the White House.

An Election With No President on the Ballot

A midterm is the general election held in the even-numbered years between presidential elections. The presidency is not at stake, and neither is most of the Senate, but the entire House of Representatives is, along with most governorships and the bulk of state and local government. That mix is what gives the midterm its distinct character.
