I thought I’d look up how union members voted in the 2010 Wisconsin midterms. The exit polls didn’t actually provided the data, but they did ask about whether you live in a union household. Not surprisingly, union households like Democrats:
That’s a strong showing for Barrett but not nearly as strong as, say, his pull of 87 percent of the African-American vote. Had unions delivered 70 percent of the union household vote to Barrett, he would have won. Russ Feingold pulled 59 percent of the union household vote in his failed re-election bid. Nationally, 61 percent of union household voters pulled the lever for a House Democrat in 2010.
