OK I wouldn't normally post political opinion pieces, but this article had me saying 'huh, that explains a lot'. It doesn't say anything that isn't really pretty obvious, nor really anything too controversial (imo). I was not fond on Trump, and I'm still not, but reading this at least made me think a bit more about why so many may have voted for him.
Have a read and see what you think. Don't be put off by the source, it's really quite a decent article.
