Correction: Walker won by, not 7; and everyone but PPP was close in their prediction: http://www.realclearpolitics.com/epolls/2012/governor/wi/wisconsin_governor_recall_election_walker_vs_barrett-3056.html
Note that none of the polls averaged by RCP for the WI recall vote are the ones being questioned in the current election - namely the alphabet soup polls commissioned and touted by the MSM.
