DAYTON, Ohio -- President Barack Obama and Vice President Joe Biden have underscored the importance of swing state Ohio in a rare joint appearance in Dayton.
Facing a tight race in the pivotal state, Obama urged supporters to work to get out the vote and help him carry their home area and Ohio.
Fire officials estimated the crowd in the Dayton park at 9,500.
Obama carried Ohio in 2008. The Democrat has campaigned in the pivotal battleground state frequently, and his campaign and supporters have devoted a lot of money and resources to Ohio.
However, Republican Mitt Romney's campaign says he has gained momentum with two weeks left until election day. Romney is scheduled to return to Ohio on Thursday, visiting a Cincinnati machine and manufacturing plant that also makes military components.
