David Gergen just made a good point on CNN about John McCain: We all laughed when the Republican presidential candidate said he didn't use a Mac OR a PC, and that his second wife did all his internet surfing for him, but McCain's luddite tendencies are screwing up his campaign and thus could wreck the country someday. Exhibit A is Clayton Williams, who was to host a McCain fundraiser but who was discovered to have once made a crass rape joke. It turns out the rape joke has long been in Williams' Wikipedia entry, ranked number three by Google in a search on Williams' name. Whoops! McCain clearly needs to learn The Google. As internet-savvy Barack Obama can testify after his jettisoning of vice-presidential-screener James Johnson, it won't weed out all the tainted associates, but it's great for that critical first cut. Clip after the jump.
