What is your state’s voter registration deadline?

There has been unprecedented excitement ahead of November’s midterm elections, and it’s caused a spike in voter registrations.

On the left, liberals see a chance to rebuke President Donald Trump’s agenda and regain at least one chamber of Congress. On the right, conservatives see an opportunity to expand on the foundation of reactionary reforms they have already set into motion during two years controlling every branch of government.

In all of this electoral excitement, it is easy to forget that in order to vote, you have to register. Given America’s notoriously backward electoral process, this means different things for different states.

Here are the voter registration deadlines you need to know, as well as some crucial information about mail-in ballots and early voting.
