Ohio senator Rob Portman will play the role of President Obama in Mitt Romney's preparations for the presidential debates, CNN reported.
Portman has done this before many times for GOP presidential and vice presidential candidates.
He's played Joe Lieberman and John Edwards for Dick Cheney in 2000 and 2004; and Al Gore and John Kerry for George W. Bush in the same years. He also played Hillary Clinton for New York State's Rick Lazio in his unsuccessful run for the Senate against Clinton, who is now secretary of state.
House Speaker John Boehner of West Chester - who is general chairman of the Republican National Convention in Tampa - is scheduled to make a speech to the delegates at the Tampa Bay Times Forum at 7 p.m. tonight.
Ohio GOP delegates in Tampa got a surprise visit Monday from a man who had run for the GOP presidential nomination, former House Speaker Newt Gingrich, who sang the praises of drilling for more Ohio oil and natural gas as a campaign issue.
Gingrich, who is making the rounds of key state delegations, argued that scientists have recently found Ohio - particularly eastern Ohio - has 42 times as much natural gas beneath its surface as previously thought; and said that Republicans could use that energy resource as a way to win votes this fall.
Ohio delegates were in a ballroom of the Mainsail Suites and Conference Center when it was announced that there was a tornado warning in the area and everyone was ordered to stay in the building.
The delegates were listening to a presentation by staff members of the Ohio Romney campaign on grassroots organizing. It was raining heavily when the warning was issued, but the rain quickly passed and there was some sunshine.
