That might be one of the root causes of the attacks -- she's aligned with Romney and she realizes Palin has the inside track for the 2012 GOP nomination.
re: Romneybots
Some Romneybots are taking particular offence to the selection of Sarah Palin over their guy, even if they don’t admit that is a central motivating factor for them. The PUMAs of the Republican Party in 08? Trying to knock Palin out as a rival to their guy for 2012? Parker and also former MA Gov. William Weld, who just announced his endorsement of the Obamanation.
I wouldn't be surprized if Romney makes a big push in the next couple days to get the 0ne elected.
