The RNC never intended to run a candidate other than Trump because he controls MAGA, which is what remains of their energized base. The primaries they held were “just in case” Merrick Garland actually did something useful and successfully prosecuted Trump for insurrection, which never came to pass.
The DNC did everything they could to prevent primary elections from occurring in various states, and bullied anyone who was floating a run into submission. This included the state dept making calls to state DNC committees to cancel primaries, or remove certain candidates from their ballots. According to them, it was an insult to Biden admin and their legacy to even suggest another candidate should run. And now look where that’s gotten us.
So no, we didn’t actually vote in primaries this year because the establishment refuses to relinquish the status quo.
