Reps. Ron Kind, Tammy Baldwin and Steve Kagen as well as former Sen. Russ Feingold and former Rep. Tom Barrett, who ran [for Governor and] lost to Walker last November, are mentioned....Interesting!
For Republicans, the obvious name is Rep. Paul Ryan, the architect of House Republicans’ controversial budget plan. It’s not clear whether Ryan wants to leave his perch as chairman of the House Budget Commtitee to make a statewide run, however.
Other GOP names being mentioned include state Attorney General J.B. Van Hollen, wealthy businessman Tim Michels and former Rep. Mark Neumann.
ADDED: WaPo's Greg Sargent opines:
But the key is that a lot has happened in Wisconsin since Feingold’s loss. The months long war in the state over Scott Walker’s effort to strip public employees of their bargaining rights has galvanized the Democratic Party in Wisconsin in a major way and — if polls showing the unpopularity of Walker’s proposals are any guide — has tilted independents and moderates in the state against GOP rule. It’s true that this battle has galvanized the grassroots on both sides, but the emerging shape of the recall elections suggest the left has more momentum and energy.A lot has happened... including the big Prosser-Kloppenburg race, which Sargent doesn't seem to have heard of.
