I didn't intend for my post to be about rural vs urban, or smart vs dumb. The point I was trying to make was that some people just aren't interested, no matter their background. You can find these people everywhere, which might explain why Trump gained in almost every county this election, even urban ones.

It's a spectrum of course. The friends you describe sound like they fall somewhere in the middle of caring about politics vs not. My point of discussion is on the people at the low end, as these are likely to swing. People past a certain threshold of attachment have had their votes locked in for years.
