Just last month Spector said something right after the "Gang of Sixteen" brokered their deal that I find very telling about where Spector is coming from.
Spector was asked if he would vote for Janice Rogers Brown and he said something like this, (I can get the exact quote if you need it) He said: "I will not announce how I will vote, I can get far more by not revealing what my intentions are"
So what that tells me is that Spector is for sale, and he has no principles
