Who wouldn't support her in the GOP? She'd be the first black woman on the Supreme Court. Do you recall the spike in the black vote in the 2004 election? More than enough incentive to build on that with a JRB appointment.
Off the top of my head, Santorum for starters (mea culpa for supporting Specter) is in a particularly bad place with conservatives and needs to regain some traction going into 2006.
I didn't say "support" her; I said "fight" for her.
Hell, the GOP Senate wouldn't fight for John Bolton for UN Secretary. They all knew him. You think they're going to the mat for some nominee they don't know?
