Polls are open in Pennsylvania. Here's how to find your polling place, drop off your mail-in ballot or see who's running in your town.

Ed Gainey, who was elected to be Pittsburgh’s first Black mayor nearly four years ago, will face Corey O’Connor, the Allegheny County Controller and well-funded son of a beloved former mayor. The primary will probably decide the general election as well, since Pittsburgh has not elected a Republican mayor in nearly a century.

Voters in the Commonwealth of Pennsylvania are going to the polls Tuesday. Ross DiMattei has what you need to know.
