Bob Casey still has a path in Pennsylvania. A rather narrow one.
Looking at Pennsylvania's Senate race, Republican Dave McCormick leads Democratic Sen. Bob Casey Jr. by about 0.5 points, 48.95% to 48.44%, with 97% of the expected vote reporting. ABC News estimates that perhaps as many as 300,000 votes are left to be counted, however, and nearly 130,000 of those are in deep-blue Philadelphia. Some back-of-the-envelope math: If we assign the outstanding votes based on the current margins in those counties, Casey would end up leading by around 16,000 votes once all votes are reported. Now, we don't know just how those outstanding votes will actually break, and whether the real total left will be around 300,000 or a bit less or more — all critical aspects to this. But this does suggest that Casey might just be able to survive even as Harris lost to Trump in the presidential race.
