Conservative blacks tend to be people of real achievement. Carson, Sowell, Williams, Thomas, Caine, Star Parker, Mia Love . . . a pretty good list.
Liberal, successful blacks tend to be people who have gotten ahead by playing the race card to extortionistic ends. Jesse Jackson, Jackson Jr., Jeremiah Wright, Sharpton, Sheila Jackson Lee, etc.
This is not always true, but there is a statistically significant tendency.
