The United States of America is supposed to be a Constitutional Republic, protecting the individual rights of every man (which is why "governments are instituted among men"). The Founding Fathers drafted our Constitution because the Articles of Confederation which had been used up to that point were "too democratic" and basically shit. Democracy = tyranny under a majority. Which is why slave-holding States were so hopped up on it, they figured that if a majority supported it, it was even possible to subjugate an entire minority under them by law. "Progressive" politicians (the Roosevelts are basically Satan) have been fucking American Exceptionalism up from day one.
If he doesn't start World War 3, his trade policies will at the very least bankrupt my State and severely impact the lives of 4/5 of the people I know, mine being the most foreign trade-dependent State in the Union (i.e. good at what we do unlike Rust Belt).
The man promotes violence at his rallies (by the way, not sure how anyone can call him a good orator, have you heard him speak? "I have good words, the best words," he's an imbecile), and promotes George Wallace-level us-against-them style politics. We need immigrants to fund the welfare State he is unwilling to cut. Immigrants, especially illegal immigrants, commit significantly less crime per capita than do natives (wow shocking right? Don't want to get caught doing something because ICE will put their ass back where they came from, who would have thought?). As a white person, ain't no white people about to pick berries, let me tell you, immigrant labor is vital for agrarian economies.
Everything the guy says is wrong, and he'll destabilize America and the world (that sweet isolationism worked out great before, yeah). He would use his position as President to "settle scores" and probably help out his mob buddies and business interests, all while making America into the shitty backwater that left-wing populism has made most South American countries that aren't Chile.
His campaign has been one big temper tantrum, he's unfit to be President, he'll fuck up everything, and I wouldn't mind at all if he weren't a factor anymore.
Fuck the East Coast.
