We'll find out Wednesday night when the show drags out the announcement of the winner for two hours. (In contrast, the shorter Tuesday night shows when the actual competition singing is done are a lot snappier. The very 1950s thing about this show that's key to its success is that the contestants never ever get to lip-sync, so it combines entertainment with the tension of sports.)
If, as expected, Jordin does win, it will be another data point for my theory of the Rise of the Mulatto Elite -- white people like minority entertainers and politicians, but they don't like them too minority, and minority cultures in the U.S. tend to be somewhat dysfunctional environments for raising children, so the best combination for becoming famous these days is to have a minority dad and a white mom.
Rage Against the Machine, the most important left wing rock band since the Clash, is a classic example with both the guitarist and singer being of mixed race. Prodigious guitarist Tom Morello is the great-nephew of Jomo Kenyatta (!), founder of modern Kenya. His father was a Mau-Mau rebel and then Kenya's first ambassador to the UN. His mom was an Irish-Italian girl from Illinois who traveled the world and married his father in Kenya. She left her husband before the baby was born. Morello was raised in Libertyville, IL, a nice all-white suburb 40 miles north of Chicago, near the Pine Meadow Golf Course, which I used to drive out from the city to play.
Similarly, the band's annoying lead singer, Zack de la Rocha, has a Latino father, who went nuts when he was 13, and so he was raised by his white mother in posh Irvine, CA. Like a certain Presidential candidate's adolescence, this pleasant white upbringing led de la Rocha to identify more strongly with his minority side.
If Blake wins American Idol, however, well never mind ...
