Clinton, Romney win Nevada

By John Whitesides, Political Correspondent

COLUMBIA, South Carolina (Reuters) - Democrat Hillary Clinton and Republican Mitt Romney won Nevada's presidential nominating contests on Saturday, and voters in South Carolina cast ballots as an unpredictable White House race moved to the U.S. South and West.

Clinton, a New York senator, beat rival Barack Obama in a hotly contested Nevada race that could give her new momentum in a seesawing nomination battle to select the Republican and Democratic candidates who will vie in the November election. The two had split the first two contests.

Romney won decisively among Republicans in a Nevada race his rivals largely skipped to concentrate on South Carolina, where John McCain and Mike Huckabee were running close ahead of voting in a campaign focused on the economy.

Clinton and Obama, an Illinois senator, traded charges of voter suppression and harassment in the final hours before the vote in Nevada, where workers at Las Vegas's casino hotels participated at nine locations on the city's famed strip.

Clinton led polls in the state for months heading into the contest, but Obama was lifted by the endorsement of a powerful labor union that represents about 60,000 workers in the state's tourist hotels.

The Nevada Democratic race, the first test of strength in a state with a large Hispanic population, was complicated by uncertainties about turnout. Only 9,000 Democrats took part in Nevada's caucuses in 2004 but turnout was reported to be much heavier this time.

Romney's convincing win in Nevada followed his breakthrough victory in Michigan last week after two disappointing second-place finishes for the former Massachusetts governor.
