Hello Flash,
You want me to provide evidence that something would have happened if a condition exists?
Ok, but you won't like it. It's a hypothetical.
A black individual is considering voting. The individual observes that the lines in the individual's district are very long and arduous. The individual decides not to vote. Apathy exists.
There is no good reason to collect drop boxes which were already there. There is no good reason to order fewer voting machines and cut back on the number of polling locations for black people. Those things are done to suppress voting.
Observing that more people came out in a recent election proves nothing. It remains unknown how many would have come out if voting had been made easier.
We want more people voting to make our country work. America needs to be more cohesive. When people vote, they feel like they are a part of things, they claim part ownership of America. Suppressing votes hurts America. Republicans should be ashamed. That is trying to make elections unfair. Republicans should be able to win by having a better message, better policies. By assuming they will lose unless they pull dirty election tricks, they are conceding that their platform is not a winner and they have to try to cheat to win.
Cheaters cheat themselves of their own dignity as they cheat others.
