From what I read, they needed 60 votes and only garnered 45 Republican votes. I think that is more than "a few liberal Republicans" who didnt go with the flow. Seems like the Vast Right Wing Conspiracy is diminishing in numbers, if not ideology. I sense the extremism in the Bush's platform is driving voters and representatives away (i.e., gay marriage, embryonic research, anti-abortion stance)
I also agree, Bush has as much teflon protection as Reagan in his hey day. His base of support sticks with him through thick and thin. He deserves that much credit.
