Former Sen. Russ Feingold (D-Wis.) announced Friday he won't run for the Senate or governor in 2012, clearing the way for other Democrats to enter those races. 

Feingold told supporters of his Progressives United PAC that he wouldn't look to reclaim one of the state's Senate seats following his 2010 defeat. He also declined getting involved with a potential recall of Wisconsin Gov. Scott Walker (R).

"While I may seek elective office again someday, I have decided not to run for public office during 2012," Feingold wrote on his website.

"After twenty-eight continuous years as an elected official … I have found the past eight months to be an opportunity to look at things from a different perspective," Feingold wrote.
