Maybe it was a timing thing. Apparently, he was promoting one of his resorts, that happens to be in Scotland, and it had little to do with the UK. I’d be surprised that Trump planned this trip on a couple of hours notice.
Then again, if he did plan it this way, he is brilliant.
This vote on the EU had been scheduled for months now. A few weeks ago Trump decided to have a ribbon-cutting ceremony for his renovated Turnberry golf course in Scotland, almost certainly knowing that it would be on the morning that the results of the Brexit vote were announced. He had already publicly discussed the EU referendum vote before he scheduled the trip for today, so its not like he wouldnt have known about the timing beforehand.
As he said during the press conference, unlike Obama and Hillary, he had a feeling that the Brits would vote leave. He also had a prepared written statement praising the vote all ready to be put out too early today. About five days ago, he also scheduled a press conference for while he was going to be in the UK, which is interesting if he just wanted to discuss a golf course. Personally, I dont believe for one second that his timing was coincidental.
