Let’s be frank. Trump stumbled a bit over Duke’s endorsement and quite honestly, if you’re not active in the KKK you probably don’t immediately recognize his name. Now every piece of gutter trash is going to crawl out of the woodworks to endorse Trump to see if its possible to make a mountain out of a flattened mole hill.
Honestly I wouldn’t be surprised if Hillary’s campaign was paying these people to endorse Trump just in case it might hurt him. Heaven knows it would be no more scandalous than her usual MO.
