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.
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'm old enough to remember Richard Nixon. They called it the imperial presidency when he was refusing to spend money that Congress had appropriated.
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.'
I think that people have to reward those individuals who are prepared to work across the political aisle. I don't see any other way; if you don't talk to people with whom you disagree, you're never going to solve problems.
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.
