LAS VEGAS — A confident Mitt Romney is looking past his GOP opponents and Nevada's caucuses.
Chief rival Newt Gingrich is bracing for defeat in a state Romney won in 2008.
Romney plans to go to Colorado Saturday morning for a campaign rally before returning to Las Vegas for a party with supporters at a casino a few miles from the Las Vegas Strip.
In a sign that he doesn't expect to win, Gingrich plans a simple statement instead of an event after the voting.
Romney cruised to victory in Florida last Tuesday, handily won this state four years ago and is heavily favored to win Saturday's contest.
Gingrich, Texas Rep. Ron Paul and former Pennsylvania Sen. Rick Santorum also are on the ballot.
