How to Register to Vote for President

The 2020 presidential election will be here before we know it, and voting laws can be complicated: they vary state by state, and are sometimes seemingly designed to be confusing. Plus, the deadlines for primary elections will be here before we know it. So what better time than now to bone up on your state’s dating rules and regulations?

The general election takes place Tuesday, Nov. 3, 2020, but the states’ primary elections and caucuses take place on different dates, some of which are confirmed and some of which have been estimated based on past caucus and primary dates. Vote.org maintains an up-to-date list of voting registration requirements. If you want to participate in your state’s caucus, you must register ahead of time. Your state’s Board of Elections or Secretary of State website will have more information about that.

There are three ways to register to vote: in person, by mail or online. All states allow registration by mail and in person. Not all states allow online registration, and only a handful allow you to register in person on Election Day.

If you live in a state where in-person registration is permitted on Election Day, be sure to bring a valid ID and proof of residency to your registration place. Also, be aware that most states require you to be a resident for at least 30 days prior to voting. So if you’re a recent transplant, you might be out of luck.

Also, if you’re planning to vote by mail-in ballot, the rules may vary, so you should double-check on your state’s election website.
