Arlen Specter's in Trouble, for Good Reason

Arlen Specter is in a dogfight to keep his Senate seat—the latest poll has fellow Democrat Joe Sestak up 9 points, notes USA Today—and no wonder. The Republican-turned-Democrat looks "like an incumbent of two parties in a year when it’s better to be an incumbent of none," writes Margaret Carlson.

Heck, he even attended a Democratic dinner last week and mistakenly thanked the "Republicans" for inviting him, writes Carlson for Bloomberg. Sestak is pouncing on that gaffe, along with the fact that Specter the Republican voted against Elena Kagan to be solicitor general, but Specter the Democrat now kinda likes her for the Supreme Court. "Is winning enough if you no longer know who you are?" asks Carlson. (More Arlen Specter stories.)
