In a quick perusal of the first google hit for a KKK website, I find no such endorsement of Bush.
The only serving politician at the national level is DEMOCRAT Byrd, Grand Kleagle of the Klan for some number of years.
I want to see that proof that the KKK endorses Bush. I do not find it.
In a continuing effort to find these KKK endorsements of Bush, I have come up empty. Since you provide no evidence to back up a claim I cannot verify, I must presume you knew you were being knowingly deceitful, and have chosen to vanish.
The US far-right definately does not support Bush. From what I've seen, he's considered a "pawn of the Jews".
