I'm not sure you're seeing the big picture. Spector is an enemy of America. Spector is loved by big media and they have made him into a high profile tool for bludgeoning republicans, not to mention his penchant for going against Republicans every time he got a chance, when he was one. The media loved kissing his ass and taking his sound bites.
Him being gone is akin to killing the wicked witch of the west. I don't care how the election goes, seeing that pos being unceremoniously thrown out is delicious, imo. This goes WAY beyond the balance of power between the parties and it is a very significant sign that even more dems are toast. I love it!
And even if a Dem wins, it’s better to have an identifiable opponent you can compete against rather than funding a leftist to udnermine your own party from within. If the Dems want to keep a liberal in this seat, they have to pay their own way now.
