Las Vegas (CNN) -- Declaring victory in Nevada's Republican presidential caucuses on Saturday, Mitt Romney again turned away from his GOP rivals and toward President Barack Obama.

CNN projects that Romney will win the Nevada Republican presidential caucuses, based on results and entrance polling.

With 71% of the votes counted, Romney held about 48% of the vote, while former House Speaker Newt Gingrich had 23% and Rep. Ron Paul had 18%. Former Pennsylvania Sen. Rick Santorum, who had largely bypassed the state, had 11% of the vote. Those numbers were gathered from vote counters at caucus sites across the state and the state's Republican Party.

Romney thanked supporters at his campaign headquarters in Las Vegas, telling them, "This isn't the first time you gave me your vote of confidence, but this time I'm going to take it to the White House," alluding to his win in Nevada in 2008.

But then he turned his attention to Obama, saying Nevada has had enough of his kind of help in fixing its home mortgage crisis and that he failed at bringing down unemployment.

Entering the race as front-runner, Romney had largely ignored his Republican rivals and focused on Obama. But as Gingrich rose to challenge him in polls, he was forced to address the other candidates in the race.

His victory speech was a one-on-one with Obama.

"This president began his presidency by apologizing for America. He should now be apologizing to America," Romney told cheering supporters.

The only allusion to GOP opponents Romney made was when he told supporters that he was the only one who could fix the economy, "unlike other people running for president."
