Johnny Harris and Andrew Prokop have created a short film for Vox, “How the Republican Party Went from Lincoln to Trump”.
Note the 2013 bipartisan agreement between “Little Rubio” and the Democrats on immigration, which many working class “white men” resented.
It’s interesting that the Republican Party was the natural supported of African Americans until the 1870s.
Vox has a 6-minute short film narrate by Amanda Taub, "Authoritarianism: The Political Science that Explains Trump". Psychological polls show that people drawn to authoritarianism expect obedience and respect from their kids, not curiosity or independence.
