Four states hold primaries Tuesday: Connecticut, Minnesota, Wisconsin and Vermont.
Polls in Minnesota — which has a special congressional election, along with competitive primaries for several contests — close at 8 p.m. CT, 9 p.m. ET.
Note: Voters in Minnesota's 1st Congressional District will cast ballots in both a special election, to fill the remainder of the late Rep. Jim Hagedorn's term, and in a primary for the seat. Here's more from Minnesota Public Radio.
