The candidate's lack of a traditional political agenda is key to his anti-political appeal.
"...the Trump crowd has thoroughly tired of conventional politics and conventional politicians. The draw of Trump’s candidacy is that he is so very obviously not bound by these conventions—that he is not a conventional politician, nor even really a politician at all. He doesn’t have policy ideas or governing plans to speak of? So what? Those are for politicians. Trump’s politics are a kind of anti-politics, and his lack of a traditional political agenda only adds to his anti-political appeal.... most of Trump’s supporters, rather like Trump himself, have put very little effort into imagining a Trump presidency, except to idly fantasize about all the ways that it would be different and awesome and better. He would be an exciting, deal-making, ass-kicker who would strike fear into the hearts of America’s enemies, and he would do this simply by virtue of being Donald Trump, in all his glorious, exciting Trumpiness.
