What congressional elections decide

USA.gov explains that congressional elections determine federal representation and which party has a majority in each chamber for the next two years. Midterms take place halfway between presidential elections. The contest therefore concerns the composition of the federal legislature rather than choosing a president, which explains why individual state races matter beyond their local constituencies. USA.gov

All 435 House seats are contested in the election cycle, alongside approximately one-third of the Senate. House members serve two-year terms; senators serve six-year terms with staggered elections, according to the government guide. USA.gov
