Homogeneity has its place, but sometimes diversity is better

Just finished skimming the "Pledge to America" released today by the Republican Party. Putting aside the policy questions (interesting proposals to "change" Obamacare and replace them with basically the same provisions!), what really struck me was the care with which the document was prepared: every other page was full of action shots, of members of Congress with their constituents, at meetings, in the workplace, and on the campaign. However, conspicuously absent in these pictures is anyone whose skin isn't the same color (or lighter!) than mine... that is, the country is 65.4% white, but 100.0% of the people in the pictures were white. Where are the blacks? The Asians? The hispanos? Like the title says, homogeneity has its place (especially when trying to discern statistical trends in meteorological data... we want the dataset to be homogeneous!)... but perhaps the homogeneity of race of the people in the 2010 Pledge is curious in its omission of the other 34.6% of America, those whose skin isn't like mine....
