Shameless Hack

Jonathan Chait writes about Sen. Arlen Specter changing parties:

When a politician switches parties, it’s customary for the party he’s
abandoned to denounce him as an unprincipled hack, and the party he’s joined to
praise him as a brave convert who’s genuinely seen the light. But I think it’s
pretty clear that Specter is an unprincipled hack. If his best odds of keeping
his Senate seat lay in joining the Communist party, he’d probably do that.
