re: #205 rightymouse

Arlen was going to lose his incumbency to Toomey in 2010 if he ran as a Republican. Switching parties gives him a chance to keep his seat. That’s what I meant by this being political expediency on his part.

Specter started as a Democrat & switched for political expediency.
He just switched back for the same reason. I don’t like fanatics, but I want you to believe something.
