My preferred view is that public is center-left on policy & representation but center-right on symbols & orientations. Other common alternatives are (1) public is centrist if measured properly, (2) public is center left but bigotry moves right, & (3) Dems strategy is bad/unlucky

Views of ideology in American public opinion should explain why the parties have long been at rough parity in candidate support. This seems to offer a useful theory: most people are center-left on policy but a large proportion of those that are judge on performance, not policy

Using open-ended responses to a question about your ideal political party to place voters on an ideological spectrum & how much they think ideologically

Dems gain in generic ballot polls, moving toward large seat gains in historical models

Good morning. I've got a banger new post out today that develops a new method for placing voters on the left-right ideological spectrum, and adds a new, "non-ideological"/affordability axis to usual way we chart & think about US voters (esp swing voters). www.gelliottmorris.com/p/not-just-l...
Not just left vs right: Most voters think about affordability and material wellbeing, not in ideological terms
Most voters want a party that emphasizes cost of living issues and makes the world a better place. Few Americans think in solidly ideologically terms. "Moderates" are mostly non-ideological.

Racial differences in policy responsiveness are small. But policy is more responsive to whites under Republicans control, not explained by class, age, or ideology but partially by party. Republican Senators' votes also better represent white constituents.
