If you look on the map, the obvious thing is aside from say Texas, all the states that support Trump are full of poor people. This can also be said for Republican support as well. Typically these states don't have high percentages of college educated people and jobs are typically under wages of middle class or at the very low rung of the middle class.

I think it shows that these people are not well informed and are more gullible than people who have better educations and higher paying jobs. Even Texas has low wages (like FL) but it's only the oil industry which props it up.
Why do poor people support Trump/Republican party while higher earners and college educated people support Democrats? Things that make you go hummm..
