Banners with "Repeal & Replace Obamacare" hung behind Mitt Romney as he slammed the President's health care law and vowed to get rid of it if he wins in November.

"The White House is not celebrating Obamacare today," Romney told a crowd of nearly 200 people at a mall in Metairie, Louisiana. "This presidency has been a failure and the centerpiece of that failure is this piece of legislation back here, Obamacare."

Romney did not mention his Republican rivals, but told a crowd of nearly 200 people at a mall in Metairie, Louisiana that he is the only candidate in the race with a plan to replace the law and get the American people "free of Obamacare."

"I'd like, instead of having the government come in and mandate price and cost controls, I would like to have individuals have a greater incentive to shop around, and make this act more like a market," Romney said.

Criticizing Obamacare as being "simply the wrong direction," Romney emphasized the need for health care to work more like a free market. He called the law another example of the President's "attack on economic and personal liberty."

"Obamacare substitutes government intrusive for the dynamics of individual responsibility for individuals being able to pursue different options and for the dynamics of a free market," he argued. "I believe in the marketplace. I believe in consumers pursuing their own dreams. I believe in individuals being able to make their own choices."

A tongue-twisted Romney drew laughs from the crowd when he accidentally slipped "y'all" into his speech when talking about the effects of Dodd Frank. He quickly corrected himself and joked, "I am not trying to act like I am from Louisiana."

As the underdog heading into Louisiana's Saturday primary, Romney made a plea to voters to get to the ballots. With 20 delegates at stake, Romney joked that he would "like all of them."

"I need you to get out and vote, alright? You got a contest coming up real soon, I would love to have your help," he said. "You got a lot of delegates here, alright. I want, well, I'd like all of them. I'm probably not going to get all of them, but I'd like to get as many as I can."
