In Pittsburgh, the city is waiting for the results for a new mayor as Allegheny County Controller Corey O'Connor takes on former police officer Tony Moreno. Voters will also decide whether or not they would like to retain three Pennsylvania Supreme Court justices. Results will begin to update after polls close at 8 p.m.

Jaime Arroyo captured 85% of votes to become Lancaster's first Latino mayor, while Corey O'Connor won in Pittsburgh 20 years after his father held the same office.

The stakes of Tuesday’s election were high: Had Pennsylvanians voted to remove the justices, the state Supreme Court would go from a seven-member court with a Democratic majority to a four-member court with a complete ideological split. The three justices’ vacant seats would not be filled until another election at the end of 2027.

While most of the statewide judicial attention has been on the Pennsylvania Supreme Court, they are not the only statewide jurists facing a retention vote.

Voters will decide whether three justices who were elected as Democrats keep their seats for another 10-year term.

Voters on Nov. 4 chose to retain three state Supreme Court justices for another 10-year term, rejecting a GOP push to oust the trio in what has traditionally been a nonpartisan contest. The Associated Press called the races just before 10 p.m. and NBC News earlier projected all three justices' retentions.
