Hotfooting it from his eight-state tour in two days, Obama matched his rival's enthusiasm and was obviously prepared to woo Ohio voters.
His strategy is to conduct a multi-pronged attack for the battleground state. Delivering targeted messages to different areas backed up by TV and radio advertising the aim is to drive up voter turn out - but will it be enough?
Reporting for euronews, ABC journalist Karen Travers said: "The polls here are very tight. Right now we are rating the state as a toss-up. We had at one point been rating it as leaning Obama. A new poll out this week shows the president up by five points, but the Romney campaign thinks that this is stil within their reach."
Believing early voters will back him, Obama stopped off in his hometown of Chicago on Thursday and lead by example by becoming the first American leader to cast his own ballot ahead of election day. Responding to journalists he refused to say who he voted for.
