I believe the GOP-E/Rove/Romney crowd made it pretty clear to her that they don’t want her (or her Tea Party ilk) anywhere around. She probably also knows that they are sinking like a rock, and that if she jumps into the fray big-time and then Romney loses, they’ll all try to blame her for the loss. Been there before. That’s the way the scumbags operate.
Bingo!
I think you’re right.
