"The point I was making was not that my grandmother harbors any racial animosity," he said. "But she is a typical white person. If she sees somebody on the street that she doesn't know. . .there's a reaction in her that doesn't go away and it comes out in the wrong way."

Wrong!
The point he was making was that his grandmother did harbor racial animosity and he then equated her with the anti-American racist Rev. Jeremiah Wright!

He threw his ailing grandmother under the bus.

It looks like he threw her under the bus again...
And this time he threw "white people" under the bus with her.
He truly was hanging with the Rev. Jeremiah Wright too long.

Could you even imagine if any white person would have said--
"But she is a typical black person"?
