WASHINGTON - US President Barack Obama and his Republican rival Mitt Romney embarked on a swirl-wind campaign tour Tuesday following the conclusion of three presidential debates, as election enters its last stretch.

The most intense campaigning will be done by Obama. He is scheduled to visit seven battleground states in two days, and two of them, Florida and Ohio, will be visited by the incumbent twice.

Obama's day starts with a campaign rally in Delray, Florida on Tuesday morning, and he is to meet up with Vice-President Joe Biden for another rally in Dayton, Ohio, in the afternoon.

After a night's rest in the White House, Obama will on Wednesday blitz Iowa, Colorado and Nevada to begin his "America Forward!" tour. He will also visit Los Angeles to tape a show with NBC's Jay Leno on Wednesday. Obama will fly overnight to Tampa, Florida on Thursday, and then on to Richmond, Virginia on the same day, before closing the tour with an evening event in Cleveland, Ohio. He will find time to go home to Chicago on Thursday to be the first sitting president to cast an early vote in person.

According to the Obama campaign, while crisscrossing the country, Obama will spend time on Air Force One calling undecided voters, rallying campaign workers and volunteers.

Romney, whose campaign lacks Obama's elaborate groundwork, will appear together with running mate Paul Ryan Tuesday in Henderson, Nevada, and head to an event in Golden, Colorado, later in the day. He will continue to visit Nevada, Iowa, and the all-important battleground of Ohio later this week.
