The discussion of Specter has got absolutely nothing to do with "conservative integrity." It just comes down to votes. Those judiciary committee votes were all 10-8. Specter winning in PA over the DEM helped preserve the GOP majority, which is why they have two more members on the judiciary committee than the DEMs have. That's all there is to it. If the GOP loses the majority, it's 10 DEMs to 8 GOPers. No Roberts, No Alito, No Nothing. This isn't an integrity contest; It's politics.
We would have held the majority even if Specter lost and Jon Kyl -- a solid conservative -- would be the Chairman instead of Specter.
What's the down side to Specter losing?
