Voters in Iowa, Montana, New Jersey, New Mexico, South Dakota, and the District of Columbia head to the polls on Tuesday for primary elections. This is also the first time former President Donald Trump is on the ballot following his felony convictions in a New York court last week.

The leading candidate for the GOP will be on the Republican ballot in Montana, New Jersey, and New Mexico. President Joe Biden will also appear on the Democratic ballot in those states, including Washington, D.C., and South Dakota.

After today, the only remaining primaries will be two contests in Guam and the U.S. Virgin Islands on Saturday, June 8.

Here’s what to watch:

Montana

In Montana, there are contested races for the U.S. House and Senate, governor, attorney general, state legislature, state Supreme Court, and several other state and local offices.

The most high-profile races include Republican challenges to incumbent Democratic Senator Jon Tester and candidates for an open U.S. House seat held by far-right Republican Representative Matt Rosendale, who is stepping down at the end of his term in January 2025.

In the presidential race, only Biden and Trump are on the primary ballots, with the option to vote “no preference” or write in a candidate.

Polls close at 8 p.m. local.

Washington D.C.

In D.C., there are contests for the Democratic presidential nominee, congressional delegates, and the City Council. President Biden is up against Marianne Williamson, Armando Perez-Serrato, and any write-in candidates.

Polls close at 8 p.m. local.

Iowa

Iowa already held its presidential caucus in January, one of the first of the primary season. It’s holding races for the U.S. House and Senate and the state House.

Polls close at 8 p.m. local.
