Did you know that only 36 of 2,380 delegates seated on the Republican convention floor were black, the fewest since the Joint Center for Political and Economic Studies began tracking diversity at political conventions 40 years ago.

Each night, the overwhelmingly white audience watched a series of white politicians step to the lectern — a visual reminder that no black Republican has served as a governor, U.S. senator or U.S. House member in the past six years.

Nationally, two-thirds of Americans are non-Hispanic whites, 12.4 percent are black and 14.8 percent are Hispanic, according to the Census Bureau's 2006 numbers.
