I suggest reading The Authoritarians by Bob Altemeyer, along with the addendums he later wrote about the “tea party” and donvict, too. You can get the PDF for The Authoritarians for free from here. Your library probably has it, too. Or you can just buy a copy, as well. I cannot recommend it enough…
