Polling precinct reports from Butler County, PA
These are second-hand reports so take it for what it is worth. Butler County has a +27% GOP registration advantage and Summit Township is even more so. Polling precincts in Summit Township have been reported to be dead. This might change as the day goes along but Summit has an older and more established population. Whether people voted more by mail needs to be seen, but the fact that a heavily Republican area hasn't seen much voting bodes well for our side.
Connoquenessing Township, which is maybe not rapidly growing in the traditional sense but definitely growing more than surrounding townships, reported a somewhat busy morning. Still heavily Republican but the demographics are changing due to an influx or more affluent developments. The newer and younger residents are more like to be Democrats or lean Democratic, especially on the issue of abortion. Neither township mentioned has a very large population and this is just anecdotal, but I have theorized that not having TFG on the ballot has popped the balloon of many of his supporters and they just are not enthusiastic to vote.
