John McCain's professed computer illiteracy is funny, but beyond that, I wonder if it's actually possible to be an effective president today without being able to access email or the internet. McCain's entire staff surely uses email to communicate virtually everything with each other. If McCain is never in the electronic loop, how is he supposed to manage that staff? All those stories about the chaotic nature of his campaign -- "a swirl of competing spheres of influence, clusters of friends, consultants and media advisers who represent a matrix of clashing ambitions and festering feuds" -- actually make a lot more sense if you factor in McCain's total lack of emailing skill.
