"Early exit polling in the Wisconsin gubernatorial recall election suggests that union household comprise roughly a third of all voters..."

"... a share of the vote that is higher than either of the last two presidential or gubernatorial elections held in the state."

Voters in the recall also tilt positively toward public sector unions in general, but not by a huge margin. Voters split about evenly in their support for changes to state law that limited the collective bargaining ability of government unions, an issue at the heart of recall effort.

Drawing broad conclusions about the shape of the electorate remains difficult due to the fact that these early exit poll reflect only morning and afternoon voters and can (and likely will) shift before polls close at 9 p.m. eastern time.

That's in the Washington Post. I'm not seeing any info on where or how the exit polling was done, but if true — as we say in Wisconsin — that sounds scary for Walker supporters.

ADDED: A Milwaukee Journal Sentinel article that went up 15 minutes ago says:

No statewide figures were available, but local election officials offered fairly similar accounts of a heavy turnout in communities large and small, in both Democratic and Republican areas.

In many places, election officials said turnout was as strong as, or stronger than, it was for the 2010 gubernatorial election. A few even compared it to the 2008 presidential election.

There was a very strong turnout in Milwaukee and Madison, the Democratic stronghold.

But Walker's base also appeared to be turning out strongly, particularly in several Waukesha County communities that favored him by more than a 2-to-1 margin in his 2010 victory over Barrett. Shawn Lundie, Waukesha County Executive Dan Vrakas' chief of staff, believes voter turnout in his county will exceed the state Government Accountability Board's estimate of 60% to 65%.

UPDATE: Drudge is headlining: "EXIT POLLS SHOW WALKER HOLDING SEAT."
