Why should anyone care what a turncoat has to say? If Specter had stayed in the party, his voice might have some marginal credibility. But since he fled the party, his voice should count for nothing. He can take all the RINOs across the aisle that he wants. We won’t miss any of them.
Specter is no turncoat, he has always been a liberal POS. The Republican voters who kept him in office when he kept stabbing them in the back are the ones to blame. Specter always showed his true colors even if the citizens were too color blind to see.
