Right, 18M people made an insane choice.
They were offered a choice of several candidates, only two of whom could possibly win - one of which would be somewhat better than status quo, and the other would be far far far worse. 18M either picked an impossible option, or walked away and got the default, which is the far far far worse option.
That is insanity
That Dems reached across the aisle to broaden the tent, or to depress the other candidate's turnout, is really irrelevant
