My reading from the article:

White Married Military Veteran Baby Boomers who watch FoxNews, use MSN for email and like Football and Pickup Trucks.

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.

Is the advanced age part true anymore? Anecdotally, my parents keep trying to get me to sign up for Facebook.

Yes, it's still true: http://www.pewinternet.org/2015/01/09/demographics-of-key-so...
