I was at a friend's birthday party last night, and another financial/political journalist and I were marvelling at the way that Obama has been able to get away with complaining about deregulation while sharing a ticket with The Man from MBNA.  Why haven't journalists pointed this out?  I asked.  He shrugged, and then said it's really McCain's fault--it's his job to make that case, and he hasn't.

Which makes me wonder:  why hasn't he?  Sheer incompetence wouldn't exactly shock me from that campaign, but is there a more strategic explanation?
