I don't know who Mitt Romney will select as his vice presidential nominee. I do know that the media is speculating about the likes of Sen. Rob Portman who is the current it-boy now that Sen. Marco Rubio seems to have faded. Of course, any Republican with an Hispanic surname seems to be under consideration, too.
As long as we're speculating, I can offer a few reasons why it won't be a politician at all.
1. What good would it do to pick a pol? They don't really bring in their home states. And in the 21st century candidates have wisely eschewed this idea which is why we've had three veeps from states with three electoral votes--Cheney, Biden, and Palin. Michael Dukakis picked Lloyd Bentsen in part in the hope of winning Texas. Uh, not so much. The days of a veep pulling in a state are over.
2. Does Romney really believe you need to be a pol to be president? In his heart does Mitt Romney, the one-term governor of Massachusetts, really believe that you need to have served in a state house or Congress to be a good president? I doubt it. If he seems to believe in one thing--and that's a big if--it's effective executives, to paraphrase Peter Drucker. I think he's just as likely to look at a CEO or someone in the military as a pol. Who? His old Bain pal Meg Whitman would have been his style had she not been a hapless campaigner and pro-choice in a party that doesn't like that in their nominees. My guess is that the Romney pick is a CEO somewhere in his FEC filings because Romney likes loyalty.
3. A CEO is a long ball, which will help. If it's August and Romney is still far enough behind on the electoral map, a long ball move like a CEO might shake up the race. Of course, it'll be a vetted, not-Sarah Palin pick. Romney, the MBA, the Bainiac, is not going to repeat the no-analysis follies of the McCain campaign. There will be decision trees and PowerPoints, thinking and analyzing, before Romney settles on a business partner--with emphasis on the word business.
