About 10-20% of the country does take this a rational, unfortunately. They are useful idiots. No one running the show truly thinks even minor voting integrity is racist but the base eats this stuff up because they still believe most of the country is racist and that all anyone thinks about is race - largely because that IS how they see everything.
Actually, all of this is designed to keep the races separate. Trump proved that the working and decent blacks, , browns, whites, and other races could work together in unity with the idea that all could share in our economy. That is why he started swinging black and brown votes to the conservative side. However, the Liberal ruling class cannot, and will not have unity about anything. They must insist on diversity, in everything, so that THEY can control.
