You have a huge number of teasies and Republicans screaming that EVERYONE should pay income taxes , so as to have "skin in the game". Consider that many Black people have such small incomes that they pay no income tax. The Republicans want to tax them. So naturally, it is economically stupid for those people who pay zero income taxes to vote Republicans so they will have to pay more. Black people are not stupid. Most believe that the Teabaggers are racists, and indeed, a kluxer who is not with the Republicans & Teasies is a kluxer who is not paying attention. Not all Republicans are racists, nor all teasies are racists. But damn near all racists are Republicans these days.
There is no good reason for most Black people in most of this country to vote Republican. None. And they don't and won't.
