Republican presidential candidate Mitt Romney says he would repeal President Barack Obama’s signature health care law and instead let states implement different programs.

Romney told voters in Louisiana on Friday that the law dubbed “Obamacare” by Republicans tramples on economic freedom and will drive up costs.

Romney focused on health care because Friday is the second anniversary of the law’s enactment. Also next week, the Supreme Court is scheduled to hear arguments on the law’s constitutionality. A major sticking point is the law’s requirement that all Americans buy health insurance.

As governor of Massachusetts, Romney signed a state health care law that required all residents to buy insurance.

Louisiana’s Republican presidential primary is Saturday.

Santorum walks back remark on Obama 2nd term

Republican presidential candidate Rick Santorum is taking back his comment that the country might as well re-elect President Barack Obama if Mitt Romney wins the GOP nomination.

Santorum emphasized Friday that he will support whoever wins the Republican primary.

Santorum was campaigning at a gun range in northern Louisiana and as he fired a .45 caliber semi-automatic Colt pistol, a woman in the audience shouted: “Pretend it’s Obama.”

Santorum was wearing protective ear muffs. He said later that he didn’t hear the remark but denounced it as “absurd.”

The Secret Service was investigating.

On Thursday, Santorum argued that Romney and Obama are so similar on the issues that Republicans might just as well vote to give the president a second term instead of casting their ballots for Romney.
