That’s a bad faith interpretation. Parties are coalitions that change over time. The neoliberal wing of the Democratic party has been ascendant since the Clinton years. But they are declining now. And the sole reason is that their brand is proving incapable of actually winning elections. If a party keeps winning, the people running the party maintain credibility and business as usual just keeps trucking along. Parties can only undergo fundamental change after losing a few cycles. It took the 3 losses of the Reagan and Bush Sr. years before something like Clinton’s triangulation strategy had any hope of winning support among the Democratic party.
