For the record, we transcribed Carter's comments here. The key sentence, which is not in any way contradicted or "nuanced" by the rest of the transcript:
I think an overwhelming portion of the intensely demonstrated animosity toward President Obama is based on the fact that he is a black man, that he's African-American.
And Jimmy Carter now:
That's not what I said. I said, those on the fringe element, who had vituperative personal attacks on President Obama, those were the ones that I included. But I recognize...
Q. Your first remarks were that overall...
No it wasn't. If you read the remarks carefully, you'll see that that's not what I said. I said that those that had a personal vituperative attack on President Obama as person, that was tinged with racism, but I recognize that people who disagree with him on health care or the environment and things like that, the vast majority of those are not tinged by racism.
The interviewer goes on to ask whether he was taken out of context, and the mean old lying bastard digs in even further, insisting "I meant exactly what I said, that what I actually said if you look at this transcript is just what I just repeated to you."
What a dumbass. Ever heard of YouTube? I guess he lost all his dignity a long time ago, so there was no point trying to preserve any by saying, "I misspoke. I apologize."
