I voted against Clinton and think she's a horrible candidate. While she may have exhibited patterns of incompetence and knowledge when dealing with embassy security, look who she's running against.
The guy who wrote The Art of the Deal said it was difficult working with Trump because he has a five minute attention span, and says he thought he was a sociopath even as he was writing the book. (Trump responded with a lawsuit.) Psychiatry professors are presenting Trump in lectures as a classic example of narcissistic personality disorder. The DSM V lists several mental disorders with symptoms that describe him perfectly. You can't pin him down on any policy, other than building a wall (across a 2000 mile border where the net traffic has started going south), dismantling the EPA, not allowing Muslims into the country, reforming the First Amendment so he can sue for libel, etc. It's mostly amorphous stuff about "hiring the best people", "making things work again", shutting things down "until we can figure out what is going on", etc. He can't keep a promise, abuses eminent domain to seize property, stiffs people once their legal fees would exceed the amount he owes, and runs scams like Trump University.
Are you comfortable being one tantrum away from a nuclear war? Ask any ambassador if they're more worried about Trump or Clinton. If you can't see all the red flags around this guy you must be a blind partisan.
