WASHINGTON (AP) -- Ron Paul cited a staggering number in the Republican presidential debate Sunday -- $15 trillion supposedly spent by the Fed "bailing out their friends." Like Mitt Romney and his claims about creating jobs in the private sector, Paul came up with that shocker by presenting an unbalanced look at balance sheets.

A look at some of the claims in a pair of lively GOP debates on the weekend and how they compare with the facts:

PAUL: "I don't see how we can do well against Obama if we have any candidate that, you know, endorsed, you know, single payer systems and TARP bailouts and don't challenge the Federal Reserve's $15 trillion of injection bailing out their friends."

THE FACTS: First, there are no fans of government-run, single-payer health insurance in the Republican field, despite Paul's suggestion otherwise Sunday. Newt Gingrich once endorsed the idea of requiring everyone to have health insurance, and Romney introduced a mandate for health coverage as Massachusetts governor. But that's a far cry from a Canadian-style health system that makes government the primary payer of people's medical bills.
