Yes, you nailed it.
This is Peggy's best column in a while. Michelle Obama's comment points out something that disturbs people. Do you remember Amarosa from the first season of The Apprentice? Something about Michelle Obama reminds me of her. This is going to be an issue in the campaign, even though people don't want to touch it now.
As I asked the author of the post you quoted approvingly, what suggests that Barack Obama is a product of affirmative action? He’s an unusually talented guy. We should oppose him because he’s a liberal, not because any successful black liberal should be assumed to owe everything to AA.
