Yes, that's exactly how the great Republican voter great suppression effort works.
There's a big problem with that complaint. As an American who has generally lived in numerous Blue cities and Blue counties, the Democrats even in Red States wouldn't stand for it. They would be taking this all the way to the Supreme Court. Anecdotally, I have lived in precincts where the majority of voters were Black and have never witnessed this so-called conspiracy to suppress the Black vote.
Remember when we were talking about media bias. You said Fox News was by far the worst. So in that biased media environment, how do you now what you are being told is the unvarnished truth? Isn't it possible liberal media looks for polling stations in Democratic strongholds where there are delays without an objective look into delays across the jurisdiction including Republican areas?
