Both major political parties have decided their presumptive nominees, and neither choice looks promising. Donald Trump has no problem with bankrupting the United States, deporting Mexican immigrants, and placing a ban on Muslims, amongst other atrocities. Hillary Clinton is far more subtle, but no less evil. She will perpetuate and grow the instability in the Middle East by keeping America in perpetual, pointless wars, and her allegiance is on sale to the highest bidder, including Wall St., weapons manufacturers, the fossil fuel industry, and big pharma.
Hillary Clinton is undoubtedly the lesser of the two evils, but those evils are evils nonetheless. I'm certain that America faces tough times under either of these leaders; Trump's way is more dramatic and quick, while Clinton will curate a slow, encroaching rot that will be organized by closed doors between special interests that could care less about the average American.
Both candidates are not clean. Trump is campaigning on a platform of hate and indifference, while the Secretary has literal blood on her hands; thousands of people who have died because of questionable weapons deals she curated, lives ruined because of policy she supported, all the while she actively participated in the regress of the working man by failing to stand up when America needed her to. You need to do a lot more than tell Wall St. to "cut it out" before it's about to ruin the entire world economy because of reckless behavior.
Some people simply do not want their names associated with Clinton or Trump, and it's understandable why. If either candidate ends up being a dud president, then those who voted for that candidate are responsible. Some people also like to vote with their morals, which might not always get things done, but if that's how they vote, that's how they vote.
Those who don't vote don't always do so out of laziness, or spite. Sometimes they are presented with two awful choices, and they don't feel comfortable supporting any of those choices.
This election presents no easy answers, and there are times that it has gotten out of control. We have a major party candidate for president who is openly sexist and racist, who makes fun of disabled people and casually jokes about killing journalists. We have another who thinks it's ok to kill anyone the US doesn't like, to uproot entire countries, leaving them vulnerable to even greater threats, who openly dismisses freedom of speech and wants to jail whistle-blowers.
It's no wonder why some people don't feel comfortable being in either camp. Of course, they could vote for Jill Stein, or by some miracle, Bernie Sanders, if Clinton gets indicted, but Clinton and Trump seem the most likely to get support from both of the major political parties in this country, and without those resources, it's almost impossible to become president of the United States of America.
