When President Barack Obama heads to Henderson, Nevada, on Sunday for several days of debate preparations, the campaign trail won't be far behind him.

Ann Romney, the wife of GOP presidential nominee Mitt Romney, will hold a rally on Monday in the city, her husband's campaign announced Saturday.

Two recent polls of the state have found Romney and Obama in a dead heat. The NBC News/Wall Street Journal/Marist poll released Thursday found the candidates separated by two points, 49% to 47%, while the CNN/ORC International poll released a week earlier found a three point difference, 49% to 46%. Both margins are within the polls' respective sampling errors.

Obama heads to the Silver State on Sunday, first holding an afternoon rally in Las Vegas. He will stay in Henderson on Monday and Tuesday, the White House said, before attending the first presidential debate with Romney on Wednesday in Denver.

The president was off the campaign trail at the White House on Saturday. Romney had announced no public events either and was at his home in Belmont, Massachusetts.

Henderson is a city of 260,000 and southeastern suburb of Las Vegas.
