The midterms determine which political party controls Congress. The two main political parties are the Democrats and the Republicans. Each party wants to win a majority of the seats in the House and the Senate.
Democrats currently control both chambers. President Joe Biden is also a Democrat, so the bills he supports have a better chance of becoming laws. But that would likely change if Republicans were to gain control of one or both chambers of Congress.
“The midterms are really important because the president can’t act on his own,” says Kyle Kondik. He’s an expert on politics at the University of Virginia. “He needs to work with the House and the Senate.”
The midterm elections serve as a kind of report card for the president. If Americans disapprove of the job he’s doing, his party will likely lose seats in Congress.
