What to know about the US primaries in Connecticut, Vermont, and Alabama

Voters in Connecticut, Vermont, and Alabama are participating in primary elections on Tuesday to select candidates for the November general elections. In Connecticut, incumbent Governor Ned Lamont faces a challenge from state Representative Josh Elliott in the Democratic gubernatorial primary. Vermont Democrats are choosing a candidate to challenge Republican Governor Phil Scott, while Republicans are vying for the chance to run against Democratic Representative Becca Balint for the state's lone US House seat. Alabama is holding special primary elections in four congressional districts under new boundaries, following a Supreme Court decision that allowed the state to implement a map previously rejected for diluting Black voters' power.

Connecticut's state primary on Tuesday features challenges to two veteran Democratic incumbents, reflecting a party trend of seeking younger, progressive alternatives. Governor Ned Lamont faces a primary challenge from state Representative Josh Elliott for his third term. In the 1st Congressional District, long-serving U.S. Representative John Larson is up against former Hartford Mayor Luke Bronin and others in his first primary contest since 1998. These primaries occur amidst a broader progressive winning streak in recent elections. Polls close at 8 p.m. ET, with results for U.S. House, governor, state Senate, and state House primaries to be provided by the Associated Press. Voters registered with a party can only vote in that party's primary.
