Five US states — Kansas, Michigan, Missouri, Virginia and Washington — are holding primary elections on Tuesday, with several closely watched House and Senate contests that could shape control of Congress in next year's midterm elections.Several Democratic primaries feature incumbents facing progressive challengers. The races are also unfolding against the backdrop of redistricting battles. Republicans in Missouri redrew the state's congressional map to strengthen their electoral prospects, while Virginia shifted its primary from June to August as part of a Democratic-backed redistricting effort that was later struck down by the courts.KansasRaceLeading candidatePartyU.S. SenateHamiltonDemocratGovernorHolscherDemocratU.S. House District 1ReinholdRepublicanU.S. House District 2CooverRepublicanU.S. House District 3DavidsDemocratU.S. House District 4TyndellRepublicanSecretary of StateDayRepublicanAttorney GeneralMannRepublicanMichiganRaceLeading candidatePartyU.S. SenateAbdul El-SayedDemocratGovernorJocelyn BensonDemocratU.S. House District 1BarrRepublicanU.S. House District 2AmbroseRepublicanU.S. House District 3ScholtenDemocratU.S. House District 4McCannDemocratU.S. House District 5VukasovichRepublicanU.S. House District 6DingellDemocratU.S. House District 7LawrenceDemocratU.S. House District 8McDonald RivetDemocratU.S. House District 9PooleyRepublicanU.S. House District 10HinesDemocratU.S. House District 11MossDemocratU.S. House District 12TlaibDemocratU.S. House District 13McKinneyDemocratMissouriRaceLeading candidatePartyU.S. House District 1BellDemocratU.S. House District 2WellmanRepublicanU.S. House District 3MannRepublicanU.S. House District 4HerreraRepublicanU.S. House District 5CleaverDemocratU.S. House District 6SmeadRepublicanU.S. House District 7HeskethRepublicanU.S. House District 8ReichardRepublicanAmendment 4No—VirginiaRaceLeading candidatePartyU.S. SenateWarnerDemocratU.S. House District 1TaylorDemocratU.S. House District 2LuriaDemocratU.S. House District 3ScottDemocratU.S. House District 4McClellanDemocratU.S. House District 5PerrielloDemocratU.S. House District 6MacyRepublicanU.S. House District 7VindmanDemocratU.S. House District 8BeyerDemocratU.S. House District 9PowersRepublicanU.S. House District 10SubramanyamDemocratU.S. House District 11WalkinshawDemocratWashingtonRaceDemocratic candidateRepublican candidateU.S. House District 1DelBeneSilvaU.S. House District 2LarsenFellerU.S. House District 3Gluesenkamp PerezBraunU.S. House District 4DureskyMcKinneyU.S. House District 5ConroyBaumgartnerU.S. House District 6RandallFoxU.S. House District 7JayapalShethU.S. House District 8SchrierMelineU.S. House District 9SmithBaslerU.S. House District 10StricklandChung
