"Trump isn't exactly winging it. Some Americans are scared, authoritarian, and racist. In a big country such as ours, there might even be millions and millions of them. Fear, authoritarianism, and racism are also strong sentiments, so it stands to reason that the people who exhibit them would be loyal Trump supporters, and unusually inclined to attend his rallies, where the themes are frequently fear, authority, and racism.
"This appeal was sufficient to win Trump the primary not because he demonstrated raw talent, but because the Republican Party is broken to the point where demagoguery is a more valuable currency than governing experience, donor networks, 'ground game' and other attributes. If Trump exhibited any talent at all, it was recognizing just how vulnerable the GOP was to being overtaken by its own Id."
Brian Beutler in The New Republic reminds readers that Donald Trump is "an almost comically untalented politician."
