Poll: Perry on top in Florida but Romney fares better against Obama

(CNN) - Hours before the second Republican presidential debate to be held in Florida in the past week and a half, Texas Gov. Rick Perry is slightly ahead of former Massachusetts Gov. Mitt Romney in the Sunshine state, according to a new poll.

The Quinnipiac University survey released Thursday morning also indicates that President Barack Obama's approval rating is at an all time low in a state that will play a crucial role next year in both the GOP nomination battle and the general election.
