That would be Justice Sonya Sotomayor. Not the flaming Liberal I would have preferred but a darn good choice that puts the Republicans in a bit of a pickle.
Any significant attempt to block her confirmation is going to make them look like the self centered obstructionists they are. Just a gaggle of arrogant SOBs ready to oppose anything simply for partisan reasons rather than considering what's good for the country.
And they call themselves patriots.
However, on the down side I see that the Center for Inquiry is extending a tentative endorsement. CFI thinks Sotomayor's stand on the Separation of Church and State is a tad murky.
Somehow I doubt she's going to line up with Scalia and Thomas and try to erase the idea that government must be neutral with respect to religion versus non-religion as well as neutral with respect to different religions.
