...Do not judge people by the color of their skin.

Ask yourself: Are these whites for, or against minority rights? The answer is obvious.

In the Democratic debates, there are no blacks. There is one mixed candidate: Barack Obama. Half black, half White. I guarantee this racial composition will not discourage blacks or Hispanics from voting en mass for a Democratic candidate, because Democrats care about minorities.
Needless to say, there isn't a systematic efford to keep blacks and Hispanics from attending the Yearlykos. Steps will be taken to make the panel look more diverse. But is it a big deal? No.
