They are openly admitting this - the republican candidate for governor said "if I'm elected the republican party will never lose another election in Wisconsin". When have you ever heard a politician make a promise like that before? It is pretty clear what he meant.
When asked repeatedly during debates or interviews they won't say they will accept the results of any election, except if they win. They are running for the positions of power that certify elections as open election deniers who claim Trump won in 2020. Do you think there is any world in which they will certify the results of a democratic win in 2024 regardless of the margin? They didn't need evidence to believe there was fraud in 2020, so they won't need it in 2024.
The only thing that might stop them is lawsuits - if judges intervene and order them to certify the results. But they might decide the constitution says that's up to states to decide however they want, and if their law allows a governor or secretary of state to certify a different winner than the total of certified votes from an election then they can't stop them. I mean, I would hope they would at least rule if a state wants to decide winners outside the democratic process, that they must first dispense with the sham of an election they will ignore. But we'll see.
2022 will be a dry run with different attempts to override the results of voters in different states, but if one or more succeeds they will supply the blueprint for all states in which election denying republicans have control over the levers in those states. If they have control in states with a majority of electoral votes, democracy may end in January 2025.
This should terrify those who live outside the US, even those who are conservative and in favor of Trump's policies, because Trump as an autocrat with complete control of the US military and economy will throw the world into chaos.
