That post rigor fragrance coming off the Republican Party is getting stronger and stronger.
Arlen Specter becomes a Democrat, which is not that big, in and of itself, because he's a reliable vote for them on most of the big stuff when he doesn't have a Republican president standing over him.
So why is it bad for the GOP? Well, they didn't see it coming. Look at Republican responses to Specter's announcement. They were scrambling around like chickens with their heads cut off. There was no message discipline at all.
Another reason for GOP doom? Specter's move strips leverage away from assclowns like Bayh, Lieberman and Nelson who like to flirt with the Republicans on close votes. The votes will be a little wider now, which means less currency for the aforementioned assclowns because the GOP will need to dip further into the Democratic caucus to find votes.
These idiots still insist checkers is the game, but Obama is playing chess and rather well at that.
