Tuesday (May 26th) is officially the deadline for all Pennsylvania voters to apply for a mail-in ballot for the June 2 primary - if you're interested in voting by mail. You must apply by 5pm TODAY (click HERE to apply).
The deadline for the ballots to be returned to your county's election office is 8pm on Tuesday, June 2 - so if you don't think it will get there in time in the mail, you can always drop it off in person anytime at your county election office.
Voters can also still vote in person on June 2, but there will be less polling places than usual, and many counties have moved polling places (temporarily) from where they normally are, so check your local county's election office.
