@hawkeye10,
O'Donnell has not "come out of nowhere." This is her third run for Senate.
She certainly has a checkered and plaided past.
BEsides, has it occurred to you that 1.) Rove is aware of how much he is hated; 2.) He is enough of a backroom boss to use reverse psychology, that is, publicly stating that the Democrat will win . . . which for those wavering voters who hate him allows them to vote for O'Donnell.
Criminals, all of them.
