Battlegrounds were races that Ballotpedia expected to be particularly competitive, interesting, or meaningful to the future balance of power in Congress. Factors that we considered in naming a battleground election included the margins of victory from recent statewide elections, how the state voted in the most recent presidential elections, whether a seat was open, if a particularly strong challenger entered the race, and more.
