Maybe he's not apologizing for racist statements because he's a narrow-minded bigot.

Why won't Lott praise desegregation? Where on earth is liberal bias when the answer to this isn't clear? To Josh, Lott’s reticence is a “mystery.” But we can solve this puzzle quite easily. Why hasn’t Lott offered a stronger retraction/apology/clarification/restatement? Almost surely, it’s because he has powerful constituent groups he just doesn’t want to offend. Marshall wanted Lott to say, “Everyone should know that I believe segregation was wrong. And I’m very proud of the progress our nation has made in guaranteeing civil rights and voting rights of all Americans, regardless of race, creed or color.” Why hasn’t Lott said something like that? Almost surely, he doesn’t want to offend key supporters. You may be surprised to think that Lott has supporters who would find that offensive. But if the sky is still blue and the grass is still green, that is almost surely why he has stayed away from such a statement. And why didn’t this obvious explanation occur to Josh? Perhaps it’s because we so rarely see frank discussions of race and GOP party politics. What ever happened to liberal bias when the groups to whom Lott wants to appeal are so rarely discussed in the press.
