LAS VEGAS — Now it's on to Colorado, Minnesota and Maine.
With back-to-back victories fueling him, Republican presidential front-runner Mitt Romney is looking toward the next states that hold GOP nominating contests as main rival Newt Gingrich brushes aside any talk of abandoning his White House bid — all but ensuring the battle will stretch into the spring if not beyond.
Shortly after losing big to Romney in Nevada on Saturday, the former House speaker emphatically renewed his vow to campaign into the party convention in Tampa this summer. His goal, he said, was to "find a series of victories which by the end of the Texas primary will leave us at parity" with Romney by early April.
Gingrich continued to shrug off Nevada's caucus results in an appearance Sunday on NBC's Meet the Press.
"This is the state he won last time, and he won it this time," he said of Romney. "Our goal is to get to Super Tuesday where we're in much more favorable territory."
Super Tuesday is March 6, when 11 states go to the polls.
But first, Gingrich must make it through Colorado and Minnesota, which both hold caucuses Tuesday.
Maine follows on Saturday during a month that promises to be as plodding as January was rapid-fire in the presidential race.
Romney will look to maintain his position of strength, if not build upon it, as rivals continue working to derail the former Massachusetts governor even as their options for doing so narrow with each victory he notches.
Former Pennsylvania Sen. Rick Santorum won the leadoff caucuses in Iowa and has trailed in the contests since then. He nonetheless insisted on Sunday that "our numbers are moving up continually."
"I think we're going to show improvement. This race is a long, long way from being over," Santorum said on Fox News Sunday.
And on ABC's This Week, Texas Rep. Ron Paul maintained the results show voters are still up for grabs.
"I get energized because I know there's a large number of people who are looking for another option," Paul said.
With votes from 83 percent of Nevada's precinct caucuses tallied on Sunday morning, Romney had 48 percent, Gingrich 22 percent, Paul 19 percent and Santorum 11 percent.
