Could Wisconsin Public Sector Unions Hand the Election to Romney?

How sweet is this?  Mitt Romney and Barack Obama are in a virtual tie in swing state Wisconsin, a state Obama won in 2008 56% to 42%.  What's going on here?  Well, the Walker Recall!  That's right--the heavily union-backed effort to recall the evil Scott Walker has energized Wisconsin Republicans, to the point where the state is in play.  Most observers feel this election is going down to the wire--and Wisconsin teachers could provide the margin of victory--FOR ROMNEY.  Delicious.
