Doonesbury by Garry Trudeau for August 12, 1972
Transcript:
Mike: Oh, Senator! Forgive me for barging in, Senator, but my name is Michael Doonesbury, and I'm a loyal supporter from back home. I was just passing through on my search for America. I just wanted you to know that I think you're doing a fantastic job. You have been voting with dignity, courage and intelligence. Come this fall, you can count on my vote! WEll, ...'bye! Man: Now that's my kind of constituent.
I think this is Senator Fred Harris of Oklahoma. If so, Michael would not have another chance to vote for him for Senator as he did not run again. But he did enter the Democratic presidential primaries in 1972 and 1976.
