I Feel Pretty - John Edwards - Sung by Mrs. Julie Edwards

One of the sillier, more trivial stories from the presidential campaign, and perhaps the one that got people on the left most consistently riled, was what started out as a pretty short blog post by Politico's Ben Smith, who reported that John Edwards had been getting $400 haircuts. Though other scandals have since overshadowed memories of Edwards' 2008 campaign, it was a big deal at the time, and it stuck around for quite a while.

Well, now we know who was responsible for the distraction and the silliness that emanated from that story: Obama's campaign. Campaign Manager David Plouffe revealed the truth in his new book, writing, "We did much less of this [opposition research] than other campaigns did, but there were times we indulged -- it was our researchers who found John Edwards's infamous $400 hair cut expenditures."
