I've come to realize that an unencumbered U.S. senator is a profound threat to the whole system. It's somebody that they can't put in a box and say, 'Oh, well, we know how this guy is going to vote.'
It's hard running as an independent. I wouldn't have won the Senate election if I hadn't been governor. I had credibility. The hard part is getting voters to the point where they think it's thinkable and not a waste of time.
I worked in the Senate in the 1970s. I worked for the Labor, Public Welfare Committee, and we had Ted Kennedy and my old boss, Bill Hathaway, and Walter Mondale.
My view of the filibuster is either you've got to lower vote edge or make people really filibuster if they feel that seriously about a piece of legislation.
