Kohl’s departure leaves Feingold, Ryan, and Neumann for open seat. Anyone else?

Yeah, that's all we needed was another Democratic open seat to fill in 2012.

jsonline: Russ Feingold and Paul Ryan, two names that loom large as potential Senate candidates, both released noncommittal statements Friday saying they will defer any decision about the race until they’ve discussed it with family members and supporters. 

“I … want to take some time over the next few days to discuss this news with my family and supporters before making any decision about how I’m best able to serve my employers in the 1st Congressional District, our state and nation," said Ryan. 

Feingold’s former chief of staff Mary Irvine provided a statement to the Journal Sentinel saying Feingold didn’t know of Kohl’s plans before today. Said Irvine: “Running for office in 2012 is not something Russ is eager to do or has been planning to do. He is very committed to his current projects -- teaching law at Marquette University Law School, Progressives United, and writing a book about American foreign policy. He will come to a decision, in the coming months, after consulting with family and friends and people in Wisconsin.” 

Former U.S. Rep. Mark Neumann is among the Republicans considering running for U.S. Senate. 

Neumann had been considering running against Democratic Sen. Herb Kohl in the November 2012 race, but Kohl announced Friday he will not seek re-eleciton. Asked if he would run for the open seat, Neumann said Friday: "We haven't ruled it out and it's certainly something Sue (his wife) and I want to think about and pray about."
