Voted in my precinct at 4 pm. It’s a pretty Republican area. For some perspective, in 2006 (the last midterm, which was disastrous for the GOP) the precinct split evenly between Santorum and Casey (Casey won the state by about 18). Rendell beat Lynn Swann by about 10 points (Rendell won the state by about 20), and GOP Rep Gerlach won the precinct by 20 points. (In 2008 McCain won about 60% of the vote)
At 4 pm (before the after work crowd hits) my voter number was just over 800 (total voters registered is 1,680). In 2006 there were barely 1,000 total votes cast the whole day.
Of course this is anecdotal, but I’m guessing there will way more than 200 people that come in over the remaining hours.
