Trump's done nothing but grab onto a formula for populism demonstrated to him, clumsily, by Sarah Palin, and the various progenitors of the astro-turf Tea Party movement, in response to an Obama presidency.  In their timid haste to field an all-white cast to take some of the steam out of this movement, the "left" has ended up promoting a weak and extremely compromised candidate for president---A lot of the reason Trump has based his demagoguery on opposition to immigrants and muslims.

Speaking of vulgarity!  It all has the smell of right- and left-hand sock puppets manipulating the voting polity for the same people; those who not only largely under-write their campaigns, but who are also the main beneficiaries of the policies both will implement when they are in office.
