Bussinessman Eric Hovde leads former governor Tommy Thompson by 2 points in the GOP primary, 31-29%. Former representative Mark Neumann continues to lose support, as he's gone from 22% four months ago to 15% now. Speaker Jeff Fitzgerald gets 9% of the republican primary vote. In a 2-person race, Hovde would lead Thompson 46-39. Among voters who have herad of him (59%) he leads Thomspon 47-21, so his support may still increase some points.
In the GE, it's a pure toss-up, with representative Baldwin trailing Hovde by one point and tied with Thompson, while leading Neumann and Fitzgerald by 4. Hovde seems to be the only one whom Wisconsin voters see favorably:
Hovde 31
Thompson 29
Neumann 15
Fitzgerald 9
Hovde 45
Baldwin 44
Thompson 45
Baldwin 45
Baldwin 45
Neumann 41
Baldwin 46
Fitzgerald 42
