@coldjoint,
Well, not to make more of this than it deserves — he was definitely warning people not to vote for his black opponent but I'm not saying his use of the term was a conscious attempt at racial disparagement. Frankly, if that were his intent, I don't think he'd be that subtle. I may be in a minority here but I put it down to a poor choice of words,
possibly exhibiting subliminal, but unproven, racism.
