Best of: clown car edition

It’s a story that begins in mid-2011 with a motley band of GOP presidential hopefuls. If you’ve forgotten, the list of candidates who at some point led the pack includes Herman Cain, Michele Bachmann, Rick Perry, Newt Gingrich, Rick Santorum and, of course, Mitt Romney. For nearly a year, the Republican primary rolled along, each week more unpredictable and bizarre than the last.  Hop into the clown car for a spin down memory lane.
