CINCINNATI (AP) -- Republican vice presidential candidate Paul Ryan and first lady Michelle Obama both drove home Ohio's status as a battleground state Monday in dueling visits that cast the past four years in two different lights.
Mrs. Obama called Ohio a key state needed to re-elect the president and emphasized her husband's accomplishments, from the federal health care law to ending the war in Iraq.
"While we still have a long way to go to completely rebuild our economy, there are more and more signs every day that we are headed in the right direction," Mrs. Obama told about 2,000 supporters at a gymnasium on the campus of Ohio Wesleyan University in Delaware in central Ohio.
Earlier Monday, Ryan told hundreds of supporters in southwestern Ohio that they're in "the battleground state of battleground states" and that they must vote for growth over stagnation in three weeks.
Ryan spoke to about 500 supporters at a Cincinnati airport on a chilly, breezy afternoon before serving them barbecue and asking, "Would you like pork?"
Ryan's airport rally means that the Republican ticket has been in a swing state six of the last eight days. Ryan and GOP presidential nominee Mitt Romney campaigned in different Ohio cities Saturday.
"Ohioans, you know you have a big say-so. You know you're the battleground state of battleground states," Ryan told the crowd. "That means you have within your control, your ability, to go find those people who voted for Barack Obama in 2008, who just aren't as impressed these days, who heard the hope and the change ... but see this is nothing but a failed agenda of broken promises."
Ryan said "the window of opportunity to fix this mess is beginning to close on us" and urged supporters to vote early so they can focus on getting others to the polls on Nov. 6.
Mrs. Obama said it was the policies that her husband inherited that put the country in the mess he's worked to fix.
"Are we going to sit back and watch everything we worked for and fought for just slip away, or keep working to move this country forward?" she said.
Mrs. Obama announced at Ohio Wesleyan and later at Cuyahoga Community College near downtown Cleveland that she had cast her absentee ballot earlier Monday. "We're one vote closer to re-electing my husband," she said.
She urged others to do the same.
"When you vote early, you can spend all that time on Election Day getting people to vote," she said. "That's the secret weapon. You're our secret weapon."
She challenged backers in Cleveland on Monday to persuade just a few more people to vote for her husband, reminding them that his margin of victory in 2008 came down to just 24 votes per precinct in the battleground state.
"That could be a couple people on your block or in your apartment building," she said. "Keep that 24 votes in the back of your mind."
Ryan visited Ohio following a stop in Wisconsin and left the state soon after lunch to head for New York.
Mrs. Obama also will be in the state Monday as the race for November gets into its final weeks.
President Obama returns to the state Wednesday with an appearance at Ohio University in Athens, while former President Bill Clinton and Bruce Springsteen will campaign Thursday for Obama in Parma.
The Obama campaign also is running a new state TV ad featuring space hero and former U.S. Sen. John Glenn, who did a radio spot for Obama last month.
