You might be waiting a very long time...
She owes McInsane everything...
Without his pick of her as a running mate, she would be a minor player in GOP politics...
I'm sure she is biting her tongue...watching this
It's a conundrum. If she attacks Juan she'll be called an ingrate and a backstabber and the media will pile on. If she should ever run again for public office, the meme will be that "Even the staunch, severe, far right McCain disavowed her." Conservatives will be on her side, but many, even here, are swayed by what MSM memes o' the day. They're like children who can't take their eyes away from the jingly keys once the presstitutes start shaking them.
If she says nothing, then she loses clout amongst her own base.
Also, she may genuinely feel a sense of loyalty to Juan, just as you would stand by a family member who was going insane.
In the end, Sarah will be Sarah. Perhaps she'll say she stands with Rand and just not mention McStain at all.
Sarah Palin repaid McCain in full, and with interest, when she gave him her endorsement in his 2010 Senate re-election run. She doesn't owe him the courtesy of a return phone call anymore.
