Specter vs. Santorum

Pennsylvania's two Senators may both be Republicans, and they may be close allies on the campaign trail. But there are some definite differences. One is willing to entertain the idea that inmates at Guantanamo Bay are human beings with rights, while the other insists that they're criminals recieving far better treatment than they deserve. One is willing to push for medical advances that could save countless sick people, while the other obsessed over a single terminally ill woman. Perhaps that's why one of them has a 54% approval rating while the other has only 45%.
