MAGA is not a third party. A third party is a political party that doesn’t run as a “ Republican” or “ democrat”. For decades both Republicans and democrats have been unified in sabotaging any efforts of a third party to run successfully, because it splinters their power. It’s well documented.
You are too wrapped up in names. Maga most certainly is a third party in spirit that took over the established viable Republican Party instead of trying to sell their unpopular ideas to the American electorate. They lied to their voters to get in.
Stop. They are not a third party. They never registered as an independent party. They ran as republicans. They are a faction of the GOP. They never ran against the GOP. They were never a separate party on the ballot. They are part of the corrupt 2 party system that supports and protects itself.
