Politicians aren't generally leaders, but rather followers. To force politicians to do something, lead where people follow you. But of course, paradoxically, this will by definition make you a practitioner of politics yourself... To quote from The Hunt for Red October, "Listen, I'm a politician, which means I'm a cheat and liar. When I'm not kissin' babies I'm stealin' their lollipops. But! It also means I keep my options open."
