I would hazard a guess that it is both. Neither party likes being reminded how little differentiates them in material terms, preferring to focus on manufactured culture wars. It would destroy the Democratic party leadership to acknowledge the center in material terms is far to the left of our left party. Neither party likes to acknowledge the cultural and ideological differences between America and the rest of the world that led (and still do) to a lack of any comprehensive social welfare and collectivized problem solving, save for problems that affect trade and the economy (the military, defense contractors, bank bailouts, border security and immigration enforcement).
