Butler County residents gathered at their respective precincts Tuesday, Nov. 4, to cast their ballots in a number of local and state races.

The decision to either retain or replace three Pennsylvania Supreme Court justices drew many to the polls across the county, but in some municipalities local races were highly contested, too.

In the city of Butler, two on-the-ballot candidates and a write-in candidate vied for the mayor seat. In Slippery Rock, a Democratic candidate competed against the Republican Mayor Jondavid Longo.
