ATLANTA -- Rick Perry said Friday that anyone with doubts about how he would govern as president should simply look at Texas.
In his first domestic policy speech as a candidate for the White House, Perry touted his record on taxes, health care and the environment during a decade at the helm of the Lone Star state. But he used the brief outline of his tenure to bludgeon his political rivals.
Perry drew a stark contrast between his record and that of Mitt Romney, his main GOP opponent, and raised the specter of the health care law Romney ushered through as governor.
"As Republican voters decide who is best suited to lead this country in a new direction by stopping the spending spree and scrapping Obamacare, I am confident they will choose a nominee who has governed on conservative principles, not one whose health care policies paved the way for Obamacare," Perry said.
"I knew when I got into this race I would have my hands full fighting President Obama's big government agenda. I just didn't think it would be in the Republican primary," Perry continued.
The 13-minute speech to the Georgia Public Policy Foundation, an Atlanta-based conservative think tank, was delivered in a laconic, low-key style. He received polite applause from the crowd, which included a number of prominent Georgia Romney supporters.
Perry offered no policy proposals, instead pointing to Texas as a roadmap for a Perry presidency.
"I have a lengthy record, and sometimes it has ruffled feathers," Perry said. "But sometimes you have to shake up the system. I am not running from my record."
Perry has been battling back after a shaky debate performance, after which he admitted that he used "inappropriate" language when he called Republican rivals "heartless." Perry was defending a Texas law that allows illegal immigrants to pay in-state tuition at state universities if they meet certain criteria.
Perry went on the offensive Friday and launched a fresh line of attack on Romney's environmental record.
"In Texas, we've cleaned the air while creating jobs and adding millions in population. Another state -- Massachusetts -- was among the first states to implement its own cap-and-trade program which included limits on carbon emissions for power plants," Perry said in his speech.
Texas, home to the nation's oil and gas industry, has taken significant steps to clean its air in recent years, offering tax breaks and other incentives to companies that install expensive pollution controlling technology. But Texas still leads the nation in greenhouse gas emissions.
Perry has fought EPA rules and regulations, insisting the agency is overreaching and meddles in state affairs. The state has challenged in court several new EPA regulations aimed at forcing heavy industry to take pollution-controlling measures.
Perry also accused Romney of relying on environmental advisers who went on to work in the Obama administration. EPA official Gina McCarthy, who works on clean air regulations, helped Massachusetts develop a climate plan when Romney served as governor.
