Yesterday I wrote a post speculating that John McCain's non-use of email might have something to do with the chaotic organization of his campaign.

A reader points out that Bill Clinton doesn't email either. Hillary Clinton's campaign in general -- and Bill's role in particular -- was also notoriously chaotic. This might be more evidence that disorganization is a natural result of having an important decision-maker who does not use the communications mechanism employed by the entire staff.
