Romney sucks and he's why I quit being a Republican, but he does want conservative judges. His constituency in Utah wouldn't even blink voting him out if he doesn't support a conservative appointment. And, Romney thinks a lot of himself, so he'll want to stay in office. Romney sucks through and through except perhaps on the issue of SC judges.
. . No idea about Murkowski and Collins. I know nothing about Maine politics (logging, lobsters, and redcoat incursions?), but I would think voting for a conservative SC judge would shore up her base. Then again, I have no idea why she's currently losing ... if you believe polls, which I don't.
