I don’t know the Janesville district, but on doing a little checking, Hulsey was Dane County Board supervisor before running for the Assembly. Dane County is where Madison is located, so one would have to presume he is a very left of left lefty.
I would imagine Janesville is heavily Dem, but leans private union as opposed to public. There was a GM plant there, now closed. People are hurting and I think they are probably open to giving Walker’s policies a chance since Hopenchange hasn’t done a lot for them thus far.
