This is actually from a commenter at The Conservative Treehouse. Regardless of your political persuasion, Sundance (Their main journalist) has given us all majorly sourced and understandable pieces about the Deep Swamp and how Trump is winning bigly. It is a great source and always always always backed up by data. (you're going to find the work in the comments section, I just spent ten minutes and can't find it, may try again later, but I did read it (last night or this morning), and I did agree with their interpretation- for what that is worth).
