You won't find a more vigorous critic of Reaganite neo-liberalism than myself; but the phenomenon of "voting against self-interest" is not limited to one party.

You won't find a more vigorous critic of Reaganite neo-liberalism than myself; but the phenomenon of "voting against self-interest" is not limited to one party. The feedback loops of electoral politics are distant and slow (especially at the national scale), and the winner-take-all voting system constrains political preferences to a relatively narrow spectrum of choices (the Overton window). These factors conspire to make voting more heavily tilted towards tribal signaling [0] than policy outcomes, and entrenched power structures (both public and private) are incentivized to maximize this phenomenon from both sides of the aisle [1].
