Arlen Specter is one sickening guy. He seriously needs to be defeated in 2010.
It'd be an interesting project to come up with trivia on this guy, how many times it sounds like he's on the verge of doing something good, only to veer off and do something sickening. It's definitely a habit.
The Republicans are sickening in general (and specifically). To defeat all of them would be a worthy goal, or to hope they wither on the vine.
