Nevada moves caucuses to 14 January
Nevada has become the latest US state to move forward its contest to pick the Republican presidential nominee.
Nevada said it would hold its caucuses on 14 January, following reschedules by Florida and South Carolina.
The states are jockeying to maintain influence in the process that will produce the Republican White House candidate for 2012.
Iowa and New Hampshire, which usually hold the first contests, are now also expected to reschedule earlier.
National Republicans initially decided Nevada would host its caucuses on 18 February, which would have made it the third contest in the nation.
But last week the pivotal swing state of Florida broke Republican Party rules by announcing its primary would take place on 31 January.
That decision prompted South Carolina to set its vote for 21 January, prompting grumbling in the party about "rogue states".
The Republican party allows only Iowa, New Hampshire, Nevada and South Carolina to stage primaries or caucuses before 6 March.
The party has threatened to punish those who flout the rules by barring some of their delegates, who help anoint the eventual nominee, from the party convention next August.
