CARSON CITY, Nev., Feb. 5 (UPI) -- Despite Mitt Romney's convincing win in the Nevada caucuses Saturday, Newt Gingrich says he's not conceding the Republican presidential nomination to his rival.

CNN reported that with 43 percent of the caucuses reporting, Romney, the former Massachusetts governor, had 43 percent of the GOP caucus-goers in his corner to 25 percent for Gingrich, the former U.S. House speaker from Georgia, 19 percent for Texas Congressman Ron Paul and 12 percent for former U.S. Sen. Rick Santorum of Pennsylvania.

The state's 28 delegates will be apportioned accordingly.

Gingrich, whose only win so far has been in South Carolina, vowed to keep campaigning all the way to his party's national convention in Florida in August, the Los Angeles Times reported.

"I am a candidate for president of the United States. I will be a candidate for president of the United States," he said. "We will continue to campaign all the way to Tampa."

Romney, who won the Florida primary Tuesday and also took New Hampshire earlier along with a virtual tie in Iowa's caucuses, thanked his supporters in Las Vegas for "a great showing" in Nevada.

He spent part of his victory speech going after Barack Obama, saying the Democratic president can't take credit for the downward trend in the unemployment rate, which has reached 8.3 percent.

"Mr. President, we welcome any good news on the jobs front," Romney said. "But it is thanks to the innovation of the America people and the private sector and not to you, Mr. President."

Paul and Santorum also showed tenacity in saying they would sally forth, CNN said.

Paul said he expected to be in second place when all the Nevada caucuses were reported and would not quit the race because there would be a "strong rebellion with my friends."

"But we're doing so well there's no reason to think about that," Paul added.

Santorum predicted he would come up with a victory in Colorado, Minnesota or Missouri in the coming week and go from there.

"I expect to win the nomination," Santorum said. "I feel very good about how it is going. This race is a long way from being over."
