President Obama will spend 48 hours campaigning “around the clock” in a frenzied effort to court swing-state voters two weeks before Election Day.

“The America Forward Tour,” beginning Wednesday, will take the president through six swing states and three time zones during a 48-hour period, the campaign said in a statement on Saturday.

Obama will hold “late night grass roots” events, “meet with volunteers” and “talk to undecided voters” in Iowa, Colorado, Nevada, Florida, Virginia and Ohio on Wednesday and Thursday.

Those six swing states will be critical in determining the outcome of the 2012 election.

Mitt Romney’s recent rise in the polls has Republicans optimistic that the GOP candidate will win Florida and Virginia. Obama, meanwhile, has had a slight edge in Ohio throughout the cycle. Nevada and Colorado are true toss-ups.

“As the President crisscrosses the nation, he will spend time on Air Force One calling undecided voters, rallying National Team Leaders and volunteers and continuously engaging with Americans across the country about the choice in this election,” the Obama campaign said in a statement.

Obama’s final stop will be in Chicago, where he will “make history by being the first sitting President to vote early in person.”

The Obama campaign has made early voting a primary focus of its get-out-the-vote efforts. Earlier this week, the campaign circulated a memo claiming the president was well ahead of Romney among early voters in Ohio.
