General elections are often the focal point of election-year media coverage as they determine control of elected offices up and down the ballot. Primary elections, however, can provide insight on future elections as they help dictate the direction each party takes.
Although many of the most competitive primaries take place for open seats or offices that are held by a different party, even high-ranking federal officeholders can lose renomination to primary challengers. In the 2014 primary for Virginia's 7th Congressional District, House Majority Leader Eric Cantor (R), ranked behind only then-Speaker John Boehner (R) in Republican House leadership, was defeated by economics professor Dave Brat (R).

Featured analysis
- Congressional margin of victory analysis: An electoral margin of victory (MOV) is the difference between the share of votes cast for the winning candidate and the runner-up in a single-seat election. In a multi-seat race, the MOV is the difference between the vote share received by the bottom-placing winning candidate and the top-placing losing candidate. Margins of victory can be used to measure electoral competitiveness, political party or candidate strength, and, indirectly, the popularity of a particular policy or set of policies. Congressional races in 2022, on average, were decided by a similar margin of victory (MOV) as in 2020. Relative to 2020, the average MOV increased in the Senate and in the House.
- Rematches in 2022 general elections: An election rematch occurs when the same candidates run against each other in consecutive election cycles. In the 2022 general election, 340 elections in Ballotpedia's coverage scope were head-to-head rematches for single-seat offices between the same candidates who ran in 2020. Additionally, 37 elections in 2022 were head-to-head rematches for single-seat offices between the same candidates who ran in 2018.[2]
