Former Massachusetts Gov. Mitt Romney is being considered the clear front-runner for Tuesday's Republican caucuses in Colorado and Minnesota.
Romney scored a big win in the Nevada presidential caucuses on Saturday, walking away with a little more than 50 percent of the vote.
While Nevada does have a sizable Mormon population, election analysts said he also carried most of the evangelical vote.
Former House Speaker Newt Gingrich, R-Ga., placed a distant second with 21 percent, but he vowed to stay in the race until the convention in Tampa, Fla., later this summer.
His goal, he said, was to "find a series of victories that by the end of the Texas primary will leave us at parity" with Romney by early April.
During an appearance on NBC's "Meet The Press" Sunday, Gingrich said his campaign's goal is to win Super Tuesday in March.
"This is the state he won last time, and he won it this time," he said of Romney's Nevada win. "Our goal is to get to Super Tuesday where we're in much more favorable territory."
Rep. Ron Paul, R-Texas finished third with 19 percent of the vote, followed by former Sen. Rick Santorum, R-Pa., who had 10 percent.
Only 32,963 voters participated in the caucuses, far short of the 44,000 Republicans who voted in the 2008 GOP caucuses.
Romney has won a total of 97 delegates. Gingrich has 30, Santorum 16 and Paul seven. It will take 1,144 delegates to win the Republican nomination.
