I am confused by this article but by reading the comments i see plenty more confusion. 
By three rings I thought he was going to address the actual three rings of Trump supporters. Before I continue I did not vote for Trump I voted Johnson, an actual liberal and by liberal i don't mean democrat. 

Ring one: Industrial workers who are interested in his ideas to revive manufacturing and coal industries. 

Ring two: White supremacists and neo nazi's who are concerned with an idea to have a racially purer country

Ring three: WTO protesters and and hardcore socialist democrats who are in an identity crisis. On one hand they are so ardent about reversing globalization and protecting world cultures, (the post structuralsts) on the other some are voted clinton cause they're friends are all focused on the support from ring two. 

Believe me, that hilary clinton is a product of the cold war democratic elite as was bush, and they're counterparts in the nocon repub circle. that's why she lost.
