Your fallacy is that personal character flaws do not translate into poor governing decisions. They most likely do.

This situation is not one of being more comfortable with the devil you know. We do know Donald Trump. He vows to jail his political rivals. He brags about sexually assaulting women. He preaches and even requests physical violence at his rallies.

Your hope, and the hope of others who voted for him, is that you do not know Donald Trump. But that is thin protection from the responsibility you took when you voted for him, because you do know him from his own words.
