In a recent article in the Guardian, postdoctoral fellow Tim Shenk argues that Donald Trump's rise within the Republican Party has historical - and often overlooked - roots. From an obscure online journal to a best-selling book from 1941 and beyond, Shenk traces the hidden and surprising intellectual path of what we now call Trumpism. Understanding this history, Shenk believes, helps illuminate Trump's popularity, his reliance on Twitter, his clashes with fellow Republicans, and more.
