Captain Ed Morrissey does just that with his post this morning in Hot Air. Says Morrissey:

Mitt Romney, a former Governor, may be best positioned of all, though, on the economy. If Romney gets selected for McCain’s running mate, he will be the only one of the four principals who has actually run a business, and run it successfully. He knows more about economic policy in both academic and practical terms than any of them, and hits Barack Obama in his key strength among voters.

Michigan is in play as it is, but as Morrissey points out, even more so with Romney.

Romney (and Pawlenty and Blunt) also have another quality that Joe Biden lacks: potential to deliver battleground states. Speculation about Michigan appears to have a solid basis in fact. In May, Survey USA tested a McCain/Romney ticket against several different iterations of an Obama ticket. Surprisingly, it beat every single possibility, but was especially strong against an Obama/Biden ticket:
vs Obama/Biden: +18
vs Obama/Clinton: +5
vs Obama/Gore: +5
vs Obama/(John) Edwards : +3

I’ve also heard that Romeny’s addition on the ticket benefits in Nevada and (I cannot believe this one) California. Romney will be terrific as an attack dog and will prove to be more presidential to voters than either Obama or Biden. His success in the private sector coupled with executive experience as a govenor of a large and important state puts his resume at the top.

I think I can speak for many republicans that in the event he is chosen, it will prompt a collective sigh of relief like no other past republican VP ever has.
