"In his desperate bid to win the presidency, Donald Trump has increasingly embraced the rhetoric and logic of the extremist far right in American history. The elements were there for all to see from the beginning of Trump's campaign—the fanning of fears about illegal immigration, about Mexicans bringing drugs and crime, about Muslims bringing terrorism; fears of outsiders, of globalization, of difference. Trumpism is modern-day McCarthyism—stoking hysteria about treason and betrayal, fomenting ever-more outlandish theories of an establishment out to get the ordinary people that he 'alone' can save, and denying the legitimacy or even decent intentions of opposing politicians. But prior to Trump no extremist movement or politician ever captured the nomination of a major political party. And none ever had the masterful command of communication media that Trump has had of television and the internet."
Larry Diamond at The Atlantic asks "whether those in Donald Trump’s party who fail to denounce his democratic disloyalty are not themselves doing great damage to American democracy."
