Mike Johnson already announced that he won't seek the minority leadership next year. There's literally no whining about the election result being fake, even from Trump himself. The Republicans are conceding all over the country.
They lost. They aren't going to do shit because they can't do shit and they know it. You can't execute a coup when the entire country resoundingly rejects you. It's the same reason Orban and Vucic had to leave.
