There has to be some safeguards in countries with nuclear weapons to limit a mad man access to them.

It's not like Hilary was any better.
Yes, she was, no matter how abysmal the choice was. Those who say that Trump was the lesser of two evils don't understand the meaning of the word evil. Those who simply couldn't tolerate neither could have voted for a third party or not voted at all. That would be morally better than enabling something evil.
As far as I am concerned there should be an extensive personality, knowledge, and IQ tests for any presidential candidate. You need far more qualifications to be a manager of a business than to be the President of the United States.
