Obama good for African American talking heads?

I'm curious ... has anyone seen any analysis of whether Obama's campaign has been good for African American pundits?

It seems like -- especially on the Republican side -- that there are more African American faces on the tv, giving their spin to events.

Genuine question ... nuttin' snarky intended.

Edit: Okay, not just me ... New York Times wrote about it this past spring:

Like the Candidates, TV’s Political Pundits Show Signs of Diversity
