Illegal Immigration is kind of problematic. We get it, like, everyone gets it. America IS BETTER THAN MEXICO, pretty much all of Central America is run by cartels and violence. So coming to America is an opportunity that they can't get down there.
So basically, 'all their countries are shit, and all the people are shit too if they don't get here legally.' Maybe you don't think that personally, but it's a growing opinion among your countrymen.
Let me tell you, as a British citizen with all the right documents, getting into the US was a massive pain in the neck. For someone from a less well-connected country, perhaps without money or the right documents, entering the legal way might be truly impossible.
But anyways, that's not my point. I know people from Southern and Central America, and they're fucking scared of Trump. Not because they're illegal immigrants (they're not) but because of the rhetoric he's spreading. He may phrase it in vaguely political terms (and yes, it is true that illegal immigration causes a multitude of problems), but the overall message he's spreading is one of hate, one of racism. These people I know? They've experienced that personally. One of them actually left the fucking States and moved up to Canada because he couldn't handle the constant harassment he was getting.
So fuck Trump. The president can't get shit done anyways (as the recent years with Obama have proven), so electing an established politician like Hillary isn't going to hurt the country too much. Not as much, at least, as the guy who is utterly loathed by the rest of the planet, because he says whatever he needs to to get the crowd riled up and on his side, even if that means turning them against a whole demographic. If he gets elected, people are going to get hurt because of his false ideals. At least with Clinton you can see she's just going to continue the same old bullshit.
