From Watergate to Wedgiegate — the Washington Post’s investigative journalism has sure come a long way. If last week’s “expose” on Mitt Romney’s prep-school bullying is any indication, from now on the fully informed voter will have to pore over every nasty prank potential candidates committed as kids.

Thanks to the Post, the punditocracy spent the better part of last week debating the forcible haircut that Romney gave a fellow student 47 years ago. The incident in question makes teenaged Mitt look like an abusive jerk. But it’s not clear what it tells us about Romney’s character nearly five decades later.
