RE: 2020 is going to be a Dem massacre.
I know you mean 2022, but you are making one assumption which might no longer be valid - that elections in future will be like they were in the past before the November 2020 elections where Trump was cheated from a victory.
This rotten and corrupt voting system is STILL IN PLACE. I’m not sure if putting your hope on 2022 is going to be realistic.
The Dems had an effort in about 5-6 known corrupt Dem cities, Detroit, Philly, Atlanta, cities in MI and Wisconsin and parts of Phoenix area and LV. Not sure if this was a scalable operation. Hopefully the purple Congressional districts in many places can still have some semblance of legality.
