At the end of the day, I'm not an American, and I understand that their way of thinking is fundamentally different to mine in many respects. (#) So I don't expect them to vote the same way or hold the same values that I do. That doesn't change the legitimacy of what I thought about Trump as a person (and why I said what I said above, particularly since we already had that piece of bullying, hypocritical garbage display a taste of that same behaviour with respect to the construction of- and issues surrounding- his own golf courses in Scotland).
I don't have time to read your link now, but yes, the Democrats sold out in the past 25 or so years. When Obama was elected and everyone expected him to be the second coming, I didn't- I knew he was a part of the same establishment that was by then already more connected with the banks and corporate interests than its grass roots.
By the time of the election, it was clear that it was going to be close- anyone paying attention should have known that. I had hoped Trump wouldn't win, but I wasn't remotely surprised when I turned on my TV first thing that morning and "Trump wins US election" was plastered over the screen. (Then again, we already had the Brexit vote which went the same way, so it was like deja-vu all over again).
(#) Too many people in the UK make the mistake of thinking that because they consume and enjoy American-produced entertainment (and speak the same language) that they "know" America. They don't. Those shows- aside from their being entertainment and not reality!- are disproportionately reflective of the urban, coastal mentality versus the culture in (what you guys call) "flyover country". America is not just New York and Los Angeles. America is not just the "cool" parts, and outside those areas it's more alien than most people recognise.
