What you say is a good general rule - but for every rule there are exceptions. Even if he fails I’d rather put my faith in an honest intelligent caring person than any of the cardboard swamp creatures who routinely screw us all. It’s a no brainer.

There’s a big difference between putting your faith in and supporting a candidate that you feel is honest, intelligent, caring person and equating them with the last chance to save this country and our world. Our country, our world should never be dependent on one man’s actions.
Would you agree that dishonest, stupid and callous leadership is a sure pathway towards destruction? A political figure is never a sole person - they are a representation of a social movement (if not they would have no political capital). What we are seeing is the rising of a sane political movement. Let’s not squander it.
