Former Sen. Russ Feingold, D-Wis., is mulling a run for retiring-Sen. Herb Kohl's, D-Wis., seat and will make a decision by Labor Day, the Milwaukee Journal-Sentinel reports.
"I am looking at it, but I feel I should take some time to think this through," Feingold told the paper. "For me the question right now is whether it's a good idea for me to go back into this sort of life."
Alternately, there has also been speculation that Feingold might challenge GOP Gov. Scott Walker next year, if Democrats force a recall election of the first-term incumbent, whose push to curtail collective bargaining rights for public employees has roiled state politics.
Feingold said, "I don't have any specific thoughts about the different offices," adding, "I'm not down to the level of which office or when, but I realize I have to come to grips with whether I would be a candidate for Senate in 2012 in the reasonably near future."
