Republican ousts incumbent Democratic senator Bob Casey after contentious and expensive race

The Republican Dave McCormick won the Senate race in the battleground state of Pennsylvania on Thursday, denying the Democratic incumbent, Bob Casey, a fourth term and expanding his party’s majority in the upper chamber.

When the Associated Press called the race at 4.09pm ET on Thursday, two days after polls closed in Pennsylvania, McCormick led by 0.4 points. The narrow margin raised the possibility of a recount, although his victory is expected to stand given his lead of roughly 30,000 votes.
