One of the more embarrassing statistics in American politics is that non-Hispanic white men make up an estimated 31 percent of the U.S. population but a whopping 64 percent of Congress. By contrast, people of color, in general, make up about 38 percent of Americans but only 20 percent of Congress. Women have it worse: just over 50 percent of the populace but 19.7 percent of the folks who decide our national laws.
