Republican Dave McCormick is the next U.S. Senator from Pennsylvania, beating out incumbant Democrat Bob Casey nearly a week ago. 

The votes are counted, the race has been called. 

And yet, Casey is refusing to concede -- prompting calls from fellow Democrats for him to do the right thing.

Meanwhile Senate Majority Leader Chuck Schumer, who will lose his post to a Republican majority in January, is refusing to allow McCormick to participate in orientation.
