We achieve greater awareness of possible leaders by having a white woman in the race and a black man on the ticket. Regardless of outcome, and I refer to what either party will do with the presidency (be he Democrat or Republican), our society now sees (in a VERY public theater) minority people stepping into leadership roles.

Let me state it one more time, in the simplest of terms I can:
Regardless of outcome, our society now sees minority people stepping into leadership roles.

This is a great thing for the advancement of equality in America. Moving forward perhaps we will see more options across the entire political spectrum.
