The first midterm election of a president's tenure historically favors the party out of power. In 2022, that's the Republican Party. Democrats, meanwhile, will this year defend their narrow congressional control, along with key governorships.
Ahead of November's general election, the major parties are picking their nominees.
Texas kicked off the midterms in March, and things really got into gear in May, when voters in 12 other states, including Pennsylvania and Georgia, cast primary ballots. Key states including Nevada followed in June.
