At one time, it was sport in the south for somewhat racist candidate to try to get the Klan to endorse a moderate opponent. The true racists would see through the scam and stick with their man, but the thought was that the moderates and Blacks would end up voting for the racist.
It a close race, it was worth the shot.
I don’t know if that is what is happening here, but it’s been done before.
Ron Paul is the major-party candidate closest to the neo-Nazis' beliefs -- he's the least supportive of the War on Terror and the most critical of Israel. Note that I am not saying he's close to their beliefs -- just closest. Perhaps least-distant would be a better phrase.
I do not believe Paul is a bigot, and he can't control who endorses him on their own time and their own dime. It's not like he's inviting Don Black up to the podium. But there is one thing that is within Ron's control, something he could do and has not -- he has not strongly, publicly, and repeatedly if necessary, condemned them and returned their campaign donations.
As others have noted, that is what Reagan did in 1980 when he learned that he had been endorsed by some Klan leaders in the South. He rejected their endorsements and returned their donations, all loudly and in public view. That is what Paul has failed to do -- with the Nazis, with the Truthers, and with all kinds of other crazies who have thrown their negligible weight behind him.
Repeating for emphasis, I do not believe Paul is a bigot or a Truther. But the fact that he does not make more of an effort to denounce them and reject their support -- and the fact that he keep appearing on a Truther radio show -- reflects badly on his judgment. The fact that he is blind to the awful impression that leaves convinces me that he is unfit to be president, a job that requires, among other things, attention to diplomacy and the impressions left by one's actions.
