Of course demagoguery cuts in both directions. That's what your 2-party system is for. ;-) It divides and separates, and you're suddenly more powerless. In Canada we have 5 parties, so demagoguery cuts 5 ways here! It also divides and separates and renders the public powerless, but in a more complicated way...which actually has some beneficial effects on moderating the process. We have long had relatively moderate governments, but the one we have now is probably the worst ever.
