Let me return to the algebra analogy: suppose you noticed mistakes in an introductory algebra textbook, and you figured out certain changes that could be made that would make the textbook much easier to understand. Would your next step be to invade a junior high school algebra classroom, interrupt the teacher, tell her that the textbook is incorrect? All you would do is confuse the students who are trying to learn something. Obviously, that is not the solution.Historically, the way that new ideas have been absorbed into the two parties is through writing- journals which are read by political thinkers. Think tanks, such as the Heritage Foundation, the Reason Foundation, the Cato Institute. I could give you plenty of historical examples, but the two most famous are probably the FDR Administration absorbing socialist ideas of the 1920s (and discarding the extremist ones) while ennacting the New Deal, and the Reagan Administration absorbing the "trickle down" ideas of 1970s conservative economists. They didn't absorb these ideas through national debates. They got them by reading journals and paying attention to the think tanks. That's how it gets done, and I think it's a good system.
