Donald Trump’s support comes from two distinct groups:authoritarians who oppose immigration and anti-establishmentvoters

Are Donald Trump’s supporters authoritarian, anti-establishment, or both? In new research into who supports The Donald, Bert Bakker, Matthijs Rooduijn and Gijs Schumacher find that Trump’s supporters are those who score low on the personality trait of agreeableness (they are more likely to support politicians who criticize the establishment), and those who are more authoritarian (they are more likely to vote for politicians who push for more restrictive immigration policies). They also find that Trump’s authoritarian supporters are likely to support other Republicans who are restrictive on the issue of immigration, such as House Speaker Paul Ryan, while the low agreeable are dismissive of such establishment figures.
