I dunno. I suspect that a fair amount of independent voters may actually want a president who is computer literate. I’m guessing that it might actually be a wash as to which way voters swing. Obama’s rallying the youth vote, which must be 95% computer literate. I don’t find the Obama’s statement ridiculous at all, but I have a clear bias.
Also, I have an extreme prejudice against a couple who share emails. I’d want to talk to John McCain, not Cindy.
