Well, David Duke DID try to run as a Republican - most notably in 1991, for governor of Louisiana. Thankfully he got the cold shoulder. That SOB lost - and I'm not sorry to hear he had to do prison time, either.
As for Dane... well, I can certainly see where he might get the notion. I wish I could believe claims it was just race-baiting, but I've seen the immgiration threads for far too long.
