With 75% of the vote in, Jason Altmire still trails Keith Rothfus by a percentage point . . . BUT Beaver County votes still aren't counted. Beaver County's site shows the Democrat up by 20 points, however, which would vault him back into the lead.
The other incumbent Dem in trouble (besides Kathy Dahlkemper) is Mark Critz, who's 1.5 points down.
