It may have been a mistake, but bringing it up now and blaming Bush for the creep and liar in that Town Meeting today, was reaching and needless, as well as illogical.
If Bush hadn't endorsed Specter, it's likely that we might have had (another) Democrat rather than Specter, but one who voted against him 100% of the time, rather than just part of the time.
(btw, I can't stand Specter. He betrayed President Bush repeatedly because he is a weasel. Blame the right guy here. Blame Specter).
Instead, we get a snake who used GOP money and votes to slither to the other side when the other side won. I'd have rather seen a Democrat win than this disgusting human being. W really blew it on that one.
