Trump's cult of personality just pulled a stunt that will ensure blacks keep voting Democrat.
It's a kind of snake-swallowing-its-own-tail effect. The Republicans want to lower voter turnout in the belief it will benefit Republican candidates. They are afraid of high black voter turnout. Then they act to make that happen, ensuring blacks will vote against them, so then they try to figure out more ways to suppress voter turnout.
For the past week or so, I have been having fun with the outright racist posts on this forum by Trumpsters, and I have made mocking replies pointing out how it is such a mystery as to why blacks won't vote Republican.
