That's a great article, and this is a great observation:
"In his 2004 convention speech, Obama concedes that we Americans have our differences. While race, geography, politics, and sexual orientation may separate individuals, he insists "there is not a liberal America and a conservative Americaâ€â€there is the United States of America. There is not a black America and a White America and Latino America and Asian Americaâ€â€there's the United States of America." The same words issued by George W. Bush's mouth would move nobody, but a boundary walker like Obama has a way of making them sound genuine."
...and the final sentence of that paragraph is one of the most persuasive aspects of a potential Obama presidency:
"The bonus point for Obama is that by calling for unity, he can also subtly reject the identity politics that have crippled the Democratic Party."
Have I mentioned how much I despise identity politics, or how much it has turned me off of the Dem party? I have practical reservations about Obama's electability, but I do see definite appeal in his potential ability to ease racial tensionss and to give the US some leadership that the world can respond to positively.
