It was laways the Republican administrations that appointed blacks on the basis of merit rather than pandering. You could always count on the Democrats to throw blacks into their designated posts at domestic graft factories like HUD and Education while the Republicans were first to appoint blacks to critical posts like Secretary of State, Secretary of Defense, and National Security Advisor.
What I could never figure out is why blacks fall for the rat con job?
I've made that argument a number of times. It ought to be obvious that Dem's want blacks "in their place" no matter their merit, whereas Republicans actually give them a real shot if they're up to it (not that Powell was, unfortunately).
