Voters in five states and Washington, D.C., head to the polls Tuesday, where they will decide a host of presidential and congressional primaries.
Montana, New Jersey, New Mexico, and South Dakota voters will decide who will win the Democratic and GOP presidential primaries, although President Joe Biden and former President Donald Trump have already clinched the nominations.
Trump is running uncontested in South Dakota’s GOP primary. In the nation’s capital, Republicans have already held their presidential primary earlier this year, but Democrats will get their chance on Tuesday.
Iowa voters have already selected Biden and Trump as their 2024 nominees but still have House primaries that will be decided next week.
Here are the key races to watch.
