If you're talking about Mia Love .. she's a mayor. Mayor's don't get prime time coverage.
Arthur Davis holds no office. Why would he be on prime time?
Condalezza Rice is the only one who would rate, but even she doesn't hold an office.
More importantly, diversity and openness are not defined by showcasing a few black faces. They are defined by the number and level of participation of other people. In 2008, only 36 of 2300 delegates were black at the republican convention. I hear that this convention has even fewer.
I hear that this republican conention will be the whitest in more than 40 years.
Compare the to the real diversity that will be on display at the democratic convention. No comparison.
It's hard to define the other side as racist when you're standing in an all-white crowd.
