Rep. Michele Bachmann of Minnesota is questioning Texas Gov. Rick Perry's record on spending. She asks Perry "how can we trust you to not go down the Obama way?"
Perry says he was able to lower Texas' amount of debt per capita since he became governor.
Bachmann also noted in her question that Perry supported Democrat Al Gore's presidential campaign in 1988. Perry says he became a Republican at a younger age than President Ronald Reagan did.
The candidates made their comments during the Bloomberg-Washington Post Republican presidential primary debate at Dartmouth College.
