there was a journalist on meet the press or one of the shows maybe over 10 years ago that argued that the conservatives had moved the overton window past the middle because the democrats had made concessions to republican positions to get deals done to keep the government working, that in order to gin up enough outrage to keep the right motivated to keep them in office the rep party had moved into far right extremist territory.
donOld gave voice to the extremists and accelerated the party's fall into maga territory.
the main question is what happens to the party, as there is only the maga faction and the old school reagan establishment type conservatives faction and maybe the free trade big business faction (the hawks/regimechange/anti rus-china-iran are out). there was sort of a balance that could be struck when the establishment held numbers advantage over the tea party wing, but now the maga wing will likely be even numbers with establishment while having the threat of primarying out any establishment rep that doesnt go along.
so who gets to keep the party name and brand? both wings need the combined numbers in order to have a majority in the congress or senate. if either breaks off to form a 3rd party they lose control of the committee chairs, and effectively lose power.
the establishment responsible government never-trumpers are not growing their numbers, so the best thing they can do is jump independent while they can still barter with both sides to buy their votes for a given bill. but short term thinking about re-election will always make them too cowardly to risk such a move.
the big problem is that at the state level maga is viable so they are fine with the rep party status quo. but anyone in a not solidly red state will be forced to pay lip service to the maga platform in order to get the funding and support of the party infrastructure which is normally worth something when not run by laura trump.
there needs to be enough elections where the dems win because of the abortion/proj2025/isolationism-appeasers issues for there to be a real change in the gop thinking. personally i hope the maga wing takes over the R brand as that will be the quickest way to force a change.
Traditional conservatives will rely on fascist movement fervor and attempt to coopt their base in an attempt to hold power without liberal or leftist compromise. They use mass politics and propaganda to spread their ideas to as many people as possible. Truth doesn't matter, only that the beliefs being spread to mass markets be adopted by enough people who come into contact with it.
Fascists, once given power by traditional conservatives, usually in a legitimate way, subtly or overtly contest conservatives and the state to hold onto power. They use nationalism and nationalist mythology, create in-groups and out-groups, and ally themselves with traditional elites/oligarchs, industrialists, and paramilitaries, once they make their play for full control. Once in control, they are able to direct the state to fund the party and the movement as their party becomes the state. This usually requires some kind of enabling act or legitimization by the state itself, whether a monarchy or entrenched aristocracy.
The background usually requires a classically liberal government to be deadlocked and the multiple leftist groups unwilling to make common cause to numerically retain/regain control of the Legislature(s). Typically, fascists were there to cause gridlock, but they always exist and they need an opportunity. They also need a charismatic leader who can act as an incarnation of the peoples' will. They are above the fray and allow followers to lodge complaints against lower-level party leaders while remaining hands-off with the Leader.
There's always tension within fascist movements/parties. Usually a few principled traditional conservatives will speak out against fascists, but they are usually few and far between because they have to get along to go along. Liberals and leftists should find common cause with principled conservatives, at least in the moment, to prevent the fascists from taking control. The military can also act as a brake on fascist movements taking over the state and government. A strong history of representative democracy can assist non-fascists, if they are willing to work together to prevent the fascist movement from taking over the state and government.
The best thing would be for traditional conservatives to fully understand that there is no "going back" without actual, real life bloodshed. Take your party back from the fascists and find common cause with people who you agree with on basic fucking things like the constitution, rule of law, and individual freedoms. Or you either get murdered in the night for speaking your mind by the people who you are going along with, or you become a collaborator and a co-defendant, assuming you survive.
I'd prefer sane conservatives to join the Democratic Party in name, force MAGA into lunatic minority status, and then the Democratic Party can split into a centrist-majority party keeping the Democratic Party name, with actual leftists creating a "Social Democrats"-esque plurality party driving politics in a progressive direction without the need for fascist authoritarianism as a "boot stamping on a human face- forever".
