Former Wisconsin Democratic Sen. Russ Feingold last week left the door open to challenging the Republican who defeated him, teasing Democrats that he may run in 2016.
Feingold spoke to party faithful on Friday at the state Democratic convention in Oconomowoc, Wis.
Feingold lost his seat in 2010, when Republicans swept the midterm elections. He was beaten by Sen. Ron Johnson (R-Wis.), who will be up for reelection in 2016. Feingold's comments at the convention, however, ruled out a run against Gov. Scott Walker (R) in 2014. Washington Post blogger Jennifer Rubin wrote on Monday that Feingold would be a good choice for Democrats for president in 2016.
The progressive senator's legacy has reemerged in recent days in the debate over civil liberties and the National Security Agency's data collection. In 2001, he was the only senator to vote against the Patriot Act.
