Please don't twist someone's words or strawman their position here. They never said rural people are uneducated, but rather less educated, which can be verified with data -- as they clearly meant formal education (high school, college, etc.).
And they definitely didn't say unintelligent. I would say I don't know where you got that from what they wrote, but I have a pretty good idea.
> And, on the note of politics, most rural people are more Libertarian than Conservative.
What we know from data is that people in rural areas tend to identify more as conservatives and vote for the more conservative party (in the US, the GOP).
