I don't know how even got elected in the first place.
Before he was a politician, he was a lawyer. He defended Ira Einhorn one of the organizers of the first Earth Day. Einhorn murdered his girlfriend and shoved her in a footlocker. She was found 16 months later in his closet. Einhorn said that it was a plot by the CIA to frame him. Specter got him out on 40K bail (only had to put up 4K). Before the trial, Einhorn skipped to Sweden. He was found living in France in 1997 and was extradited to the US in 2002, due mainly to the efforts of John Walsh (America's Most Wanted). As part of the extradition, Pennsylvania had to retry him (he was tried and sentenced to death in abstentia) and had to not go for the death penalty. Instead of being put to death, he lived a comfortable life for almost 25 years, due to Arlen Specter.
Specter has been a RINO from day one. I was so pissed at Bush for backing him during his last election. Shows that the majority of people in PA are idiots.
