Appearances matter, and the GOP simply doesn’t look that friendly. Regardless of what is true, when an arena full of white people cheers jabs aimed at the first African American president, it feels wrong. This may not be a conscious recognition, but the subliminal is powerful. It was with a deep, inner sigh of relief that white Republicans heard Romney say that he had wanted Obama to succeed because he wanted America to succeed. Bless the speechwriters.
To paraphrase the original question — why doesn’t the Republican Party have a Barack Obama? — courageous Republicans might look for clues in their children’s science book, assuming they still have one. There they’ll learn that ecosystems thrive and are most productive when there is biodiversity. The same can be said of political parties. An all-white party will not long survive in a diverse environment.
The strongest and fittest are those who adapt, and that species for now goes by the name Democrat.
