Feingold sizes up presidential race

"'I'm not interested in getting out there just for the sake of saying, 'This would be a fun thing to try.' It's a far too serious thing for that,' said Feingold, best known nationally for the 2002 campaign law that he authored with Arizona Republican John McCain. 'And who knows? If get out there and I'm not the right guy, I might just cause problems. So maybe I'll end up being just somebody helping somebody else. But I want to help.'"

Sen. Russ Feingold was overwhelmingly re-elected by Wisconsin voters 55%-44% in November.
