Who is the average Donald Trump supporter? (per Facebook data)

This seems kind of like a joke, but I also want to point out that such a conclusion isn't supported by the data.

Just because certain categories are more likely to support Trump doesn't mean they overlap with other categories.

And then you have the massive problem with the fact that this is Facebook data. My guess (partially based on their advanced age) is that Trump supporters are less likely to use Facebook or have Internet access.
