美国共和党总统参选人转战西部

U.S. presidential contender Mitt Romney is marching forward with his reclaimed front-runner status into a series of smaller nominating contests starting later this week in Nevada.
 
The Romney campaign will concentrate its efforts Wednesday on two upcoming caucus states, Minnesota and Nevada, which will hold the next nominating contest Saturday.
 
The former Massachusetts governor had a message for President Barack Obama after a commanding victory in the Florida Republican primary Tuesday.
 
Nevada could bring another boost for Romney, who won the state's 2008 Republican presidential caucus.
 
Romney won 46 percent of the Florida vote on Tuesday, far ahead of his closest rival, Newt Gingrich, who took home 32 percent of the vote.
 
But Gingrich was confident after the Florida poll and is moving his campaign efforts on to Nevada Wednesday, as promised.
 
Nevada may provide some much-needed support for Ron Paul, who is trailing the Republican field of presidential hopefuls. The Texas congressman skipped the final days of campaigning in Florida to get a head start rallying support in Nevada and Maine, which begins a week-long caucus on Saturday.
