George Bush appointed Colin Powell and Condaleeza Rice based on their merit. Democrat President’s appoint blacks to token positions to look good from an HR perspective.
Democrats run black candidates in gerrymandered black districts. They rarely run black candidates in white districts.
Republicans run black candidates in white districts based on their merit. Tim Scott and Allen West will win their seats with minimal black support. Tim Scott won his primary against Strom Thurmond’s son in the deep South. Both will win.
The message is that Republicans look at the person; Democrats look at the color of their skin.
