Ann Althouse defends Rush Limbaugh from accusations of race baiting

As Hendrick Hertzberg points out, for people like Althouse the only significant form of racism left in America appears to be the racism of liberals who patronize black people (by electing them president apparently), while falsely accusing conservatives of racism, when they're the real racists (Harry Reid! The 1964 Civil Rights Act, enacted over the objections of the Democrat Party etc etc).

Hertzberg also points out that he didn't claim Limbaugh was a racist -- only that he used "racist coding." In any case, what sort of person listens to the audio clip to which Hertzberg links and feels impelled to defend Limbaugh?
