Voters in six states go to the polls Tuesday in a round of primaries that will test the Democratic Party's ideological direction and the reach of President Donald Trump's endorsement.

Primaries are being held in Connecticut, Minnesota, Vermont and Wisconsin, with special elections in South Carolina and Alabama, Fox News reported.

The clearest ideological contest is in Minnesota, where Democrats choose a Senate nominee between centrist Rep. Angie Craig and progressive Lt. Gov. Peggy Flanagan. The Associated Press framed the race as a direct referendum on which wing of the party is better positioned for November.

In Wisconsin, Democrats select a nominee for governor in a field that includes state Rep. Francesca Hong, a member of the Democratic Socialists of America running on economic relief. Her canvassers have leaned on the cost of gas, groceries and rent, an argument that echoes the campaign that carried Zohran Mamdani to City Hall in New York.

Competitive House primaries are also on the ballot, including Connecticut's 1st District and the Democratic race in Wisconsin's 3rd District.

Alabama's contests are unusual: candidates are running to represent newly drawn districts that do not take effect until January 2027, while sitting members serve their current districts through the end of this year.

Polls close first in Vermont and South Carolina at 7 p.m. Eastern, then Connecticut at 8 p.m., and Minnesota and Wisconsin at 9 p.m.
