(CNN) - GOP presidential candidate Rick Perry said if he had made any mistakes thus far in the campaign, it was "probably ever doing one of the" debates.
"All they’re interested in is stirring it up between the candidates instead of really talking about the issues that are important to the American people," Perry said on Fox News Tuesday.
Answering criticism over his debate performances, the Texas governor has repeatedly said Americans weren't looking for the "slickest" candidate or the smoothest debater in the race.
Perry, who rolled out his flat-tax plan Tuesday in South Carolina, again said he used the wrong word when describing people who disagreed with him on immigration as "heartless."
He first dialed back his remark in late September after facing a strong reaction from within the GOP.
Perry originally made the comment at the Fox News/Google debate in Florida after taking heat for signing off on a Texas law that allows tuition credits to certain illegal immigrants at public universities.
In the interview Tuesday, Perry also took a shot at former Massachusetts Gov. Mitt Romney, who sparred with Perry during the CNN Western Republican Presidential Debate last week in Las Vegas.
Continuing his attack on Romney as a flip-flopper, Perry said: "In his own words, he says 'Listen, I need to say whatever I need to say for whatever office I'm running for'."
