What would you do in his situation though? Keep fighting and split the Democrats which all but ensures Trump will win, or do you submit to the establishment and hopefully prevent a person who's last job on his resume is "reality TV show host" from winning the Presidency?
It's really the most real "lesser of two evils" scenario that I have encountered since I have been able to vote.
I don't think Trump is a good candidate. I should make that very clear to start with. The one exception to this are his stances towards Russia and the UK, at least for the time being. That said, I don't think any presidential candidates or presidents have been good since Ron Paul.
However, I do think he is better than Clinton. Anybody is better than Clinton. She's endlessly corrupt, she's a warmonger and she is one of the least consistent politicians I've ever seen. For example, she's been going on about the validity of Black Lives Matter, and yet in the past she has consistently been one of the most anti-black politicians in modern history. It's not just the fact that she's corrupt that worries me, but the fact that she has plenty of others in the palm of her hand, as the outcome of the FBI investigation proves.
If Hillary weren't a candidate I probably wouldn't care so much about this election, but she is. I know that if she gets elected the US will become more involved (or at least they will cease to become less involved) in the middle east, and the UK along with the entirety of NATO will be dragged along with you.
This is what surprises me about Bernie's endorsement. She is one of THE WORST examples of a politician today. She is every negative stereotype of politicians rolled into one. The fact that Bernie would endorse such a witch makes him almost as bad in my eyes. He is contributing to the evil, and for what? To try and keep the Democratic party together? If he were true to his words, if he were real man of the people then he wouldn't care about the party at all! Absolutely disgraceful.
Trump to me is terrible for many reasons, however, I won't say I disagree with every single thing he has said. He has been right on quite a few of his statements and I do really like that he isn't nearly as "bought" as Hillary and many other politicians. However, I think you are being just a bit over dramatic about Clinton. Corrupt? Oh yeah, the most recent FBI investigation showed that pretty easily. Inconsistent? Definitely, she is a professional flippy-floppy. Warmonger? Maybe, we've seen a lot worse though. One of the most anti-black politicians in modern history? Come on now, she probably is really a racist old white lady (the 2008 election cycle comes to mind...) but her policies have not been actively anti-black.
Also, if you're worried about Hillary dragging the USA into a war with NATO and the UK riding shotgun, than you should really be worried about both candidates. Trump's so called "foreign policy" will at best alienate countless nations around the world, and at worst will likely result in at least one war breaking out. Trump being elected as a Republican will mean he will have to kowtow to the Military Industrial Complex that has his party by the balls if he wants to get anything done during his presidency, so I think that some good ol' fashioned 'Murican warmongering will be happening whether Clinton or Trump gets elected.
To me it boils down to this; this next president will most likely be able to select 2 or maybe even 3 Supreme Court justices, which no matter who you talk to on either side of the political spectrum all agree this is going make a huge difference in the judicial landscape for years and years to come. My ONLY concern now is to prevent that shift from pushing the USA into a far-right wonderland, where abortions are made illegal, gay marriage is rolled back, and corporations develop complete rights of person-hood.
As to Bernie's endorsement, I'm going to go with my parent's classic response, "I'm not mad, I'm just really disappointed."
