It’s about hurting the people you want to be hurt: sluts, illegals (but only from countries you don’t like), black people, liberals, gays, etc. There is so much hatred and fear and animosity built up over years of listening to Fox News and Rush Limbaugh, and he is the person voicing all their pent up emotions. He makes it OK to be the assholes they have not felt comfortable being before.

It’s not necessarily that he is their ideal person (though for some people a giant blowhard asshole is), it’s that he furthers their agenda. He packs the courts, lowers taxes, punishes the correct people, fights communism.
