I was up late with some friends last night engaging in the usual political banter and the question of the moment: who will — or rather who should — Obama pick to be his vice presidential running mate? What should be the criteria? After much deliberation, it seemed to us that the usual geographical and even demographic criteria just didn’t play out. What seems most important is for him to find someone with lots of foreign policy or governing experience who doesn’t dilute or distract from Obama’s overall message and profile. The V.P. choice should appeal to those who are on the fence about Obama (rather than just those who already fully support him) but not to the point of being a jarring counterpoint. The choice should complement Obama but expand the pool of interest, be someone who’s a fighter but not a distracter. So we’re liking Jim Webb.
