It's also important to realise no one actually knows why, if they did they'd win every election going.

We're at a time pretty much world wide where immigration is being used as the excuse for lots of things and as a result people are moving more towards the right in their voting. It isn't just an America thing it's happening in the vast majority of places. To try and then assign all the reasons on relatively localised issues and get a correct answer is always going to throw up a lot of falseness.

Another thing is people aren't all that logical about issues and don't put in the research to determine how true things are. If you keep repeating something you're more likely to believe it's true (part of the explanation as to my first point) whether it is or is not true. How people feel is much more important than the actual truth & those feelings need to be explained. It's much easier to blame smaller groups of people than yourself or those running the show.

That and Clinton is awful.
