I agree with you that the main focus must be on Biden, and on his destructive policies.
But I think there is value in talking about possible (probable?) election fraud in 2020. True, no court is going to do anything about it. But maybe, just maybe, the talk will make the Dem’s think twice about committing open fraud in 2024.
That’s wishful thinking, if you openly cheat and win elections and nothing is done about it, what makes you think the other side will voluntarily disarm themselves.
If anything they will cheat more without the fear of getting caught, what stops them.
This is why talking about past cheating is a waste of time, you can’t clean up the election process without winning elections first and complaining about cheating has proven to be a losing strategy.
You play the game with the rules that exist, not the rules you wish existed. Either the Republicans get in the game and develop winning strategies for ballot harvesting, voting early and universal mail in voting or they will cease to exist at the national level.
