Who Are Trump's Supporters?
Some Small Excerpt:
“Trump is the staunchest champion of the white working class that American politics has seen in decades.” Combine their class with their self-declared conservatism and you have the people Lipset described.
According to Lipset, “authoritarian predispositions and ethnic prejudice flow more naturally from the situation of the lower classes than from that of middle and upper classes.” These were the people who formed the base of the Nazi labor unions (Lipset was writing in 1959), the White Citizens Councils in the segregated American south, and race rioters in England. Lipset continued, “working-class groups have proved to be the most nationalistic and jingoistic sector of the population. In a number of nations, they have clearly been in the forefront of the struggle against equal rights for minority groups, and have sought to limit immigration or to impose racial standards in countries with open immigration.” This, of course, describes a Donald Trump rally almost perfectly.
