"The whole Democratic Party keeps going back to 2016. "
If they had a collective Common Sense gene, they should never forget the Dim disaster of 2016 and learn from it.
Just as people contemplating appeasement should never forget 1938 and "Peace In Our Time".
But I hope they keep going back to 2016, for all the wrong reasons. Their diminishing base will cheer while thinking Americans will say "Holy shit. Are they crazy?"
