I'm pretty fuckin' terrified of this election, honestly. I'm not big on either candidate, Clinton doesn't fully line up with my views (though she hits most of them), and Trump is a giant fuckwit that has absolutely no experience in politics and only got this far on name alone. But Trump as president would be incredibly dangerous for the entire world. Every progressive idea we've had in the last fifty years would likely be completely undone, I have every reason to believe he'd start a new war, he'll probably completely trash the economy, and god only knows what he's gonna do with foreign affairs. Trump winning would send the world into a much worse condition.
Right now, all my social media stuff is constant urging to get out and vote for Hillary (as voting third-party would be tossing the vote away and just help Trump), and yeah, it IS important to vote, everyone should vote Hillary, because at least she won't be Trump. It's just stressful to be constantly reminded that an egomaniacal failed businessman non-politician could take the oval office.
As for his chances of actually winning, I hear a lot of different opinions. Some say he could win, others say he absolutely can't win. I take this is as a combination of opinion and looking at the numbers differently.
