2020 will be confirmed in 2024. Trump will probably not survive to the election and the rigging will be more skilled from practice. Only Marxists will be “elected” again. The Republican Deep Staters will be flushed out of the system in the years following 24 while retaining one or two token opposition like McConnell and McCarthy. 24 will begin the migration of the algorithmic rigging down ballot which will be complete during the following election or two barring Divine intervention or a national breakup. This assumes, of course, that Biden&Co. does not manage to start a nuclear exchange.
If the military does not step in the picture you just painted will become reality. Then civil war will erupt.
