Unless you actually wander through the bizarre social media world of Trump supporters, you will really have no idea just how out there and paranoid their perception of reality is. I was amazed to see that they are becoming increasingly convinced that the London mayor Sadiq Khan has ties to ISIS, the implication being that he was somehow behind the terror attacks. There’s no proof of this whatsoever, of course, but it was a story in Breitbart, which means it must be true. Furthermore, as Trump, like his core followers, gets most of his news from Breitbart, does he think that the mayor of London is affiliated with ISIS? Only tweets will tell.
