I've heard, and not yet found details, that she's been reversed "a lot". Until I know something about the cases and her rulings (always assuming there's anything at all to it) I don't know what that means. It suggests (granting it's true for the moment) that she's either not good, or else out of the legal mainstream in her decisions. The second wouldn't have to mean I didn't support her, of course. Anyway, still looking for substantiation and details.

Being on the Supreme Court means never being reversed by a higher court, after all.
