Johnson faces Dave Westlake in the September Republican primary. The winner will take on 18 year incumbent Democrat Senator Russ Feingold.
In my humble opinion, should the November election turn on economic issues, the Republicans will win (Feingold's 30 years in the political world is a liability in this scenario). On the other hand, should the election turn on debates, Russ will be tough to beat.
I hope we have a serious competitor to Herb Kohl.....
