No one can look into another person's heart, of course. But many of Obama's most prominent critics have talked enough about the president and race to provide plenty of evidence about where they're coming from.  And no one has been more revealing of their inner demons than Rush Limbaugh; who can forget this classic too-much-information rant?

We are being told that we have to hope he succeeds, that we have to bend over, grab the ankles, bend over forward, backward, whichever, because his father was black, because this is the first black president.

Strikingly, the same day Carter made his supposedly controversial comments about racism and Obama critics, Limbaugh (9/15/09) was engaged in all-out race-baiting over a schoolbus fight that was initially reported as a racial incident:

It's Obama's America, is it not? Obama's America, white kids getting beat up on school buses now. You put your kids on a school bus, you expect safety, but in Obama's America the white kids now get beat up with the black kids cheering, "Yay, right on, right on, right on, right on," and, of course, everybody says the white kid deserved it, he was born a racist, he's white.

If that's not an expression of a racial animus, what would qualify?  Why is it more controversial to criticize people who issue hateful rants like this than it is to make them in the first place?
