If it's necessary to join a caucus and get a committee assignment, I'll do it.
My desire is to be as independent as I can be, as long as I can be, subject to being effective.
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.
One of my life principles is that if something isn't working, doing something harder isn't necessarily going to produce the same result.
