I also suspect that Ron Paul will support Palin as payback for her support of son Rand. Palin has been masterful in garnering paleo support in much the same way Nixon did by forcefully backing Goldwater in 64.
As a matter of fact (or theory), there was a lot of coverage about Palin being a former Buchanan and Paul supporter. I think she is hawkish on foreign policy, but rooted in realism. She has a libertarian streak in her. She could probably unite the three strands of the Republican party: limited government, foreign policy, social conservatism in a way not seen since Reagan and Lee Atwater’s 88 campaign.
Ron Paul on Sarah Palin:

As for soon-to-be departing Alaska Gov. Sarah Palin, Paul dismisses her supporters as “more establishment, conventional Country-Club type of Republicans.”
“I wonder whether she’s energizing the 15-20 year olds,” Paul muses. “That would be a question I would have. Because she doesn’t talk about the Federal Reserve and some of these issues. She doesn’t talk too much about personal liberties, civil liberties, getting rid of drug laws, attacking the war on drugs, punishing people who torture.”
