It came down to a 6th-ballot choice between a black guy (Michael Steele) and a guy who until a few months ago belonged to a whites-only club (Katon Dawson), and the Republican National Committee members narrowly picked the black guy, 91-77.
For me, there's a symmetry to this. In 2004, the Republicans held their convention in New York, shortly after Illinois state senator Barack Obama stole the show in Boston with his keynote speech. Steele, then lieutenant governor of Maryland, was given a keynote slot by the GOP, and he gave a pretty good speech -- but the rank-and-file Republican delegates loved it, and treated him like their equivalent rising star to Obama.
