Malcolm in Denver: VP Biden

I thought it would happen while I was on the flight from London to Denver. But I've arrived and happened to still be up, checking my emails and the blogs 1am Mountain Time, and saw the speculation on Obama's VP become hard fact. Obama has chosen Joe Biden. The Obama website confirms it all. So we now have someone with huge foreign policy experience on the ticket. Is that a good thing? Does it not really matter, as it is Obama's face and rhetoric that has and will continue to make the most positive impact worldwide; rather than policy specifics and diplomatic networks?
