Margin for error makes it go the other way.
Nobody bothered to ask me or anyone in my family that say to heck with the unions and praise Governor Walker.
I support Governor Walker.
That's an important point. It's a relatively small sample (500 likely voters), so the margin of error is +/- 4.5 points. The result is well within that.
It's still disappointingly close. And given this is a presidential election year, turn-out will be heavy.
