Michelle Obama plans another trip to Las Vegas

WASHINGTON - The Obamas are getting to be regulars in Las Vegas.

Michelle Obama is being dispatched Tuesday to Southern Nevada for a campaign event, according to a Las Vegas official with the Obama for America organization.

An advance team has been scouting locations, the official confirmed. More details were expected today.

As far as can be determined, the first lady will take part in a single event, and there is no fundraising scheduled for the visit, the official said.

Michelle Obama last was in Las Vegas on May 1 for a rally and a private fundraiser to kick off President Barack Obama's campaign for re-election.

Before that, she brought her two daughters to Las Vegas at the end of March for a private visit.

By most measures, Nevada is considered a must-win state if Obama is to fend off presumptive Republican nominee Mitt Romney to win another four years in office. Obama himself has made eight trips to Southern Nevada since he was elected.

Republicans were quick to react. GOP spokesman Darren Littell said Obama "hasn't lived up to the promise of his 2008 campaign - no amount of campaigning will change that."
