Last month I finished reading Angler by Barton Gellman and it was an interesting read on Dick Cheney. What does that have to do with Rob Portman? In the book Gellman mentions that Portman played the part of John Edwards to prep Dick Cheney for his Vice Presidential debate.
That fun fact of the day is relevant now as the Romney campaign has tabbed the Ohio Senator & frequently mentioned VP candidate to play the role of President Obama in preparation for their debates in the run-up to the election.
Apparently Rob Portman is the guy you want mimicking your political rivals. Does this mean anything? Probably not, as Portman has a long history of this, but hey, maybe Romney gets to closely vet Portman a bit more?
