Mitt Romney and Herman Cain in Middle of Circular Firing Squad

When candidates got a chance to ask other candidates questions at the Bloomberg debate Tuesday night, most of the fire was aimed at Mitt Romney and Herman Cain, the front-runners in national polls.

Cain called on Romney: "Can you name all 59 points in your economic plan, and does it satisfy criteria of being simple, transparent, fair and neutral?" (Romney didn't try.)

Newt Gingrich questioned Romney about the rationale for proposing capital gains tax cuts for people earning less than $200,000.

Jon Huntsman assailed Romney over his credentials as a businessman "who breaks down businesses, as opposed to creating opportunity and jobs." Romney refuted that characterization, noting among other things that his company financed the Staples office-supply chain as a start-up.

Rick Perry chided the Massachusetts governor about Romneycare's similarities to Obamacare.

Ron Paul opined that Cain was soft on the Fed because of Cain's former position as a member of the Federal Reserve in Kansas City, Mo.

Rick Santorum, criticizing Cain, among others, for supporting the Fed's role in the 2009 bank bailouts, asserted that the Washington outsider's "lack of experience" could put him at a disadvantage in governing and saying "no."

Michele Bachmann lit into Rick Perry, recalling his role as a Texas campaign manager for Al Gore in 1988, and presiding over tax increases in the Lone Star State.
