Trump won the primary because he identified groups of people unhappy with the current direction of the country--rural voters sick of being the acceptable targets of progressive elites, blue-collar workers feeling hopeless about the disappearance of manufacturing jobs and other well-paying jobs that don't need a college degree, well-off white guys feeling culturally threatened by immigration--and he locked in their votes with laser-guided pandering bullshit.
Elect Trump to get back at all those namby-pamby liberals who think they're so much better than us because they eat 'organic' and identify as pansexual giraffes and stomp all over us 'cause they care more about the endangered whosawhatsit than people's livelihoods.
Elect Trump to singlehandedly stop the world from getting hot, flat, and crowded.
Elect Trump to show those illegals what-for, because they're goddamn cheaters who should've come in the right way, and our own fucking party's happy to let businesses fire us and hire them.
Elect Trump because he beats the politicians at their own dirty games. He's a winner and he'll clean up the system so America can start winning again, instead of fighting with one hand tied behind our back like we've done ever since Korea, because fucking liberals like Clinton would rather line their own pockets with globalist money than fight for Americans.
Elect Trump because he won't let some priggish progressive moralizing get in the way of him saying whatever he wants, and he won't let it get in the way of making America great again, either.
Trump baited his promises with just enough emotional truth to build a base of true believers willing to overlook that he's a cruel, impotent, ignorant bullshitter who can't give them what they want and will probably wreck the country if he tries. Oh, and the media helpfully spread this message for Trump with billions in free advertising because the stuff he was saying seemed so fucking outlandish to them.
And then Trump ran roughshod over an incompetent, disorganized, unserious GOP primary field by virtue of having this untouchable base.
That's not a street fight. It's a con job. And while the con man is discovering that the scope of his con is limited, that he got this far speaks volumes about the depth of the emotions he manipulated. Trump won the primary because America is broken and he promises to be the fix-it man, even though he's got nothing but spit, duct tape, and dynamite.
