You're the one who just brought up race. What does skin color, ethnicity, have to do with anything?
Hillary ran, McCain needed to find a woman (any woman, even one who believed she could see Russia from her porch); Barrack won, the GOP needs a black candidate (any conservative black man will do).
The issue is not race, it's all about tokenism. The GOP is overwhelmingly white in a nation becoming more diverse each year, to win it needs to change the
perception that it is intolerant of Americans of color, the GLBT community, and non-Christian creeds.
Good luck, no one will believe painting a tiger with polka dots will fool anyone.
