Feingold for Governor in 2014?
Preferably Kohl retires in 2012 and Feingold wins that seat in what will hopefully be a more favorable environment.
Maybe?
Especially since it looks like the whole Wisconsin Democratic Party is going to be annihilated this election cycle.
I'm not a fan of Feingold, and think the whole "maverick" schtick is a bunch of crap, but he would be a much better Senator than Herb Kohl. He wanted that seat basically as a hobby, just "something to do." Maybe if he wakes up from his nap, he'll decide to retire.
As far as Feingold running for Governor, Scott Walker will be very tough to beat. A Democrat in Wisconsin needs about 60% out of Milwaukee County to win statewide. Walker has won Milwaukee County as County Executive (in blowouts), and it would be tough for any Democrat to get the necessary votes there to beat him statewide.
Of course like hinted in succeeding posts, there is a strong chance Kohl will retire in 2012, and depending on the environment the Democrats stand a shot at holding that seat. However, like also said that also depends on the candidate the Democrat's run as their bench in Wisconsin at the moment seems awfully thin.
