Richard Spencer comes from a wealthy Southern landowning family.

The social base of fascism has always been diverse including everyone from small business owners to farmers to bureaucrats, solders and some working-class people.
Trump's hardcore base had a household income of around $70,000 which is higher than the national median and included plenty of well-educated people.

I think some liberals like to believe that Trump supporters are all ignorant hillbillies or basement-dwelling malcontents. It is a comforting narrative because you can blame the election on a group that is seen as obviously retrograde. But the truth is that a lot of Trump supporters are quite successful and likely work with you in nice offices and have degrees on their wall. Affluent people can be racist just as much as or even more than working-class people.
EDIT: Also, I doubt that anyone pushed for trying to reach out to the hardcore racist contingent in the Trump coalition. These folks will never vote for Democrats. The Trump voters we need to reach out to are the Obama-Trump voters. These are swing voters who I doubt are white nationalist types especially if they voted for Obama, sometimes twice!
