Joanie Caucus is a fictional character in Garry Trudeau's comic strip Doonesbury.
She finds that her recently acquired feminist beliefs clash with his idea of how a wife should behave, and she promptly walks out on him and her two children.
There she spends several years living with the other characters while running a day-care service for local children (whose parents often aren't too thrilled when their little girls come home talking about Women's Rights).
After becoming a lawyer, Joanie spends many years working for Congresswoman Lacey Davenport, and marries Rick Redfern, a reporter with the Washington Post.
Starting in the fall 2011 Joanie worked as volunteer coordinator for the real-live candidate Elizabeth Warren's campaign to unseat Massachusetts Senator Scott Brown.
