You can see the bias against Republicans in these analyses of why Trump increased support from African Americans from 2016 to 2020. The only anti-Trump point of substance that Vox offers in its article says is that the rate of African American income growth from the beginning of (this is critical) The Great Recession until 2020 was lower than the rate of white income growth. That sounds bad until you realize that Vox used a deceptive time period: from The Great Recession is a time that started during Obama before Trump became President. The more honest and fair time period of analysis would have been only during Trump's presidency, when African American income actually grew at a faster rate than white income!
