And therein lies the problem Dems still haven't faced. Your party got arrogant and didn't see Trump as a true threat. They cut corners, underestimated the opposition, and had the unthinkable(to them) happen. Trump won. But instead of accepting it, they immediately decided Trump must have cheated, hence the Mueller investigation.
Trump won/Hillary lost, no matter how you phrase the argument, it's the same thing. Instead of coming down to earth, the Dems went into overdrive on absurdity. And I can't put a number on it as you always attempt to do, but I can tell you that to at least some Americans, the extremes they've gone to are not attractive. Honestly, I think the next election will be interesting.
