Republican solidarity appears to be at stake as more prominent Republicans have thrown their support to Democrat Senator Barack Obama in the campaign.
Former Senator Charles Mathias of Maryland is the latest to lend his support to the Democratic nominee.

The selection of Sarah Palin is one factor turning off some Republicans.
Former Senator Mathias told The Washington Post:

“For me, that person is Barack Obama.”
