The end of the story - the 1970s onward part in the Wiki article - is just sad.
All in all he sounds like a man who made one
horrible mistake - not so much in campaigning against desegration of schools, but in calling out the National Guard and in using those infamous words - and wasn't man enough to own up to it.
However, I'm not sure how true that is.
Faubus also ran for President in 1960 on a "National States Rights" ticket; that's missing on the Wiki. (He received 45K votes, of them 28K votes in Arkansas where he polled 7%.) Actually quite a lot of that Wiki article is
very apologetic.
