That's really dumb to say that a Christian should not be involved in government in any way. Where's your scriptural support for that?
It's impossible for there to be anarchy and people to be free. When you have anarchy some criminal and his band of thugs takes control. It happens every time the government, military, and rule of law disappears from a society. Think of Mexico with the cartels or Somalia with their warlords.
