Michelle Obama plans a campaign appearance today in Dayton for her husband's re-election bid.
The First Lady is scheduled to appear at the Dayton Convention Center at 3:10 this afternoon. Tickets for the event are no longer available.
Mrs. Obama also has a stop schedule at a high school in Westerville, a suburb of Columbus.
Ohio is a must-win ticket for the president, who must tread carefully in a state where unemployment has continued to drop under Republican Gov. John Kasich.
Kasich lives in Westerville, the site of Michelle Obama's early afternoon speech.
Westerville has also been the site of contentious school levy campaigns that epitomize the state's school funding problems.
The First Lady's visit follows campaign stops last week by the President and Vice President Joe Biden.
Republican challenger Mitt Romney also made three stops in Ohio last week.
