If you like small government you need to work hard at having a strong national defense that is not so militant. Personal liberty is the purpose of government, to protect liberty - not to run your personal life, not to run the economy, and not to pretend that we can tell the world how they ought to live.
I like Mitt Romney as a person. I think he's a dignified person. But I have no common ground on economics. He doesn't worry about the Federal Reserve. He doesn't worry about foreign policy. He doesn't talk about civil liberties, so I would have a hard time to expect him to ever invite me to campaign with him.
