The Obama campaign has tapped Sen. John Kerry (D-MA) -- the party's presidential nominee in 2004 -- to play Mitt Romney in the mock debate preparations, according to officials in the campaign and in the senator's office.
Kerry is a logical choice here, having both home-state experience with Romney and being in the spotlight himself with debates against George W. Bush in 2004, as well as a series of high-profile debates against Republican Bill Weld in 1996.
The Romney campaign hasn't announced who will play Obama in its mock debates. But Sen. Rob Portman, who is one of Romney's VP possibilities, played Barack Obama for John McCain in 2008.
