Trump has given us an unflattering portrait of mental health in America. There are the truly mad, like Flynn, and then the bandwagon followers. Some members of Congress appear to be both.
Perhaps, if Trump were to be elected again - and the crazy thing is that, if the "thing" that used to be the Republican Party nominates him, then we KNOW he'll say he won in November '24! If that isn't scary, you've forgotten how to be scared.
But, if he were to, god forbid, end up in the Oval Office again, he can install Flynn in a new Cabinet position, Secretary of Religion. You know he would.
