Obviously, not all aspects of the Barney Frank Experience are going to play in Peoria, but I think his fighting spirit is something that progressive politicians in jurisdictions of all kinds could learn from:
Voters don’t have a great deal of knowledge about the issues, or a great deal of interest in acquiring knowledge about the issues. But they are human beings, equipped with our species’ excellent ability to read the emotional states of other human beings. If they see a politician acting defensive about his “side” in an argument, they conclude that this critics are probably on to something. If they see a politicians acting outraged and hitting back fearlessly, they’re likely to conclude that he has nothing to apologize for.
