To be completely fair here: the reports are all saying that Trump’s location that day was not public information. So either this guy got real lucky to show up on a day Trump was playing golf, or else he had some information that very few other people had. Okay, granted, Trump plays golf a lot, so it could just be a coincidence. Still, it would be kind of ironic if it turned out someone in his own campaign was leaking info to the crazies.
