I’m live blogging today’s Republican presidential debate from Iowa. One of the first questions asked was who is paying too much in taxes: the wealthy, the middle class or the poor?

The responses:

Alan Keys: non-answer

John McCain: “I don’t know exactly who’s paying the most of the burden.”

Mike Huckabee: non-answer, followed by fair tax posturing

Mitt Romney: “I don’t stay awake at night worrying about the taxes rich people are paying, to be honest.” “We need to reduce the burden on middle income Americans.”

Fred Thompson: non-answer, followed by snipes at Romney, “My goal is to get into Mitt Romney’s situation where you don’t have to worry about paying taxes anymore.” He then seemed to answer that the wealthy are carrying too much of the tax burden by noting the wealthiest five percent of Americans pay more than 50% of overall taxes.

Tom Tancredo: non-answer

Ron Paul: the poor “It’s the middle-class that is being wiped out.”

Hunter: non-answer, followed by attack on the IRS

Giuliani: non-answer, flat tax, tax rates

Quick analysis: Romney, in a rare move, shows the most political courage by answering in favor of the poor, but keeping it in a Republican, fiscally conservative context. Huckabee gives a surprisingly weak answer.
