Two possible reasons for this:
1.) Obama is looking for a war with, or possibly within, the GOP. The Tea Party and Conservative rank and file will demand (rightfully so, imho) that the GOP Senators destroy her in confirmation hearings. Either they do that and get into a nasty (and more importantly, distracting) fight with the Obama Administration, or they get into a fight with their base.
2.) They’re floating her name to make the actual choice look good (or at least much better) by comparison.
“Theyre floating her name to make the actual choice look good (or at least much better) by comparison.”
Golly! What’s next with these miscreants? A science adviser that predicted a billion people starving to death by 1985? A communications czar that wants censorship? The next thing you know they’ll put a pedophile in charge of school safety !
