My guess is that McCain will pick Pawlenty. His Tom Ridge
comments were a serious trial balloon, so Ridge is a possibility
unless the conservative reacton dissuaded him (which you can never
guarantee with McCain). There's an outside chance he'll pick Eric
Cantor. Cantor would be the least bad, but I take Quin's point
about the political risks.
Obama seems to be inching toward Tim Kaine, foolishly in my
view, though it could help him flip Virginia. If he wants a more
seasoned foreign-policy hand, he could choose Sam Nunn. Or he could
try to replicate Walter Mondale's success and have an Obama-Ferraro
unity ticket.
UPDATE: Of course, the Ridge comments could just as easily have
been a trial balloon for Giuliani as for Ridge himself.
