Here's the dirty secret:
Fraud machines go undetected until they get too big to hide much longer. Guess where that usually happens? Democrat held urban areas.
Look at Florida and notice how that's mysteriously moving away from being a swing state, despite being a similar target of interstat-migration like TX, AZ, and GA. Why is that? Hmmmm, maybe its because the Republicans built a political machine of their own there after the 2000 race and structured election laws such that ensure Democrats are at a disadvantage.
The whole system is corrupt. All of it. Top to bottom election fraud. It's not omnipresent and happening all the time, but everything is set up so that more often than not the "right" candidates make it and the "wrong" candidates never make it past the primary. You think removing the establishment republicans is going to happen in 2022? Think again. Two years from now, the GOP will have reoriented themselves away from Trump - no matter how many people they alienate in doing so - because Trump isn't well liked by politicians, their staff, or donors. That's who's vote counts in this country. Not the vote of the serfs, the votes of the political class.
