MILTON FRIEDMAN: Why we don’t need to throw the bums out. “It’s nice to elect the right people, but that’s not the way you solve things. The way you solve things is by making it politically profitable for the wrong people to do the right things.”

Politicians are at best semi-autonomous. They mostly respond to external forces. If you want them to behave differently, change the correlation of forces. That can be done by taking over state parties, by primarying people, by changing the culture and all sorts of other ways.
