Dem poll: Walker recall battle is a dead heat - The Plum Line - The Washington Post
"Today’s poll — like polling released by the other side — should be evaluated as part of the ongoing spin war over the course of the recall campaign, which is designed to help influence the outcome, or at least to prevent public polling from creating premature impressions that the race is over.
Indeed, even neutral Wisconsin political observers believe that public polling of this race may not be predictive, since turnout in a mid-year gubernatorial recall election is impossible to anticipate. What’s more, in this case turnout is expected to be far higher than in the 2010 election that installed Walker in power in the first place."
