I see this correction a lot around here. I think it misses the point, because in a Red vs Blue system, whichever party replaces old Blue, in part or whole, is still called Blue. Obviously that is OP’s intended meaning.
For example, tea party libertarians, Christian nationalists, and MAGA populists basically took over the GOP, replacing old school Neo-cons fiscal conservatives etc, but everyone still calls them Republicans. Likewise, the DSA candidate Zohran Mamdani ran in the primaries as a Working Families / Democrat candidate, and in the general election as a Democrat.
When someone refers to future Dem strategy on Lemmy IME you can safely assume they agree that old Dems suck, and they need no additional reminders, as if they haven’t been paying attention for over 20 years. They’re referring to what happens next, the new party we elect to replace the old do-nothing status-quo controlled-opposition Democratic Party. I hope that makes sense.
