Jackson is not a complete idiot, like Sharpton. Its about the money and the fight. Olberman is the very expendable host on MSNBC when Jackson starts demanding a black host be hired. The gutless at MSNBC will oblige and look for the guy with the worst numbers. Hey Olberman, your it.
Actually that would be Mathews or Tucker of one of the others.
Olbermann is the top of MSNBC ratings. The hustle has not evolved to that yet.
