Seeking to motivate his supporters to go to the polls, Obama will cast his ballot early in his hometown of Chicago, Illinois, on Thursday. First lady Michelle Obama submitted her absentee ballot on Monday in Illinois.
During the tour, the president plans to visit six of the nine battleground states, making stops
Wednesday in Denver, Colorado, and Las Vegas, Nevada, before heading to Tampa, Florida, and Richmond, Virginia, on Thursday. He will end the 48-hour tour in Cleveland, Ohio, on Thursday.
