HOW YOU CAN VOTE:

You can make sure you are registered to vote here.

In-person voting begins at polling locations from 7 a.m. through 8 p.m. Tuesday, April 23.

Mail-in voting is over, however you can still submit your ballots at drop-box locations listed by your county.

If you are voting for the first time, proof of identification is required, either with a photo or not, according to the commonwealth's website.

Some accepted forms include a driver's license or PennDOT ID card, a U.S. Government issued I.D. or a U.S. passport. A full list of accepted I.D.'s can be found here.

If you don't have an I.D. with your photo on it, you can also use an I.D. that includes your name and address like a firearm permit, a current paycheck or a current bank statement.

If you have voted at your polling location before, you do not need to bring an I.D. to vote, per the commonwealth's website.

Pennsylvania is one of 10 states that has a closed primary system, which means if you are not part of the Democratic or Republican parties, you will not be able to vote tomorrow.
