Republicans don’t have the balls, or the infrastructure connections, to cheat.
Cheating on the industrial scale that occurred in 2020 requires a veritable army of morally deficient people with no conscience. Republicans don’t have that (nor would we want it). Democrats, on the other hand, have just such a criminally-minded army in the inner city “BLM brigade.” Just watch how they instantly swarm businesses to pick them clean at the first opportunity. People like that have no problem cheating in elections.
