Moderate Democrats have been consistently inconsistent for decades. They have been rightfully critical of the prospect of a progressive presidential nominee: A progressive could alienate centrist voters, drive up voting rates among conservatives, and imperil the reelection chances of House Democrats in districts Trump won in 2016. Moderate Democrats have wrongfully refused to be self-critical of the prospect of a moderate presidential nominee: A moderate could alienate progressive voters into not voting or voting third party, drive down the voting rates of the party’s younger and nonwhite base, and fail to win back young or liberal white working-class swing voters who swung from Obama in 2012 to Donald Trump in 2016. To be a progressive in a party with a moderate is like being on a team with someone who sees all your deficiencies and does not see any of his own deficiencies, who always takes the credit when he wins, and never accepts blame when he loses.
