From a British point of view, I think it's a disaster. As a woman, I find his comments about women in general to be pretty appalling(wtf even about his own daughter?!), but enough about that. As a European, I also find it worrisome at how he'd consider nuking Europe over the whole Syria/ISIS/Muslim issue, even if he doesn't end up doing that, it's still worrying at how a man of that calibre gets access to the nuclear codes. I know both the Democratic and Republican parties have numerous stances on equality and gay marriage but I find his Vice-President's, Mike Pence, stance to be completely stupid and just plain dumb. He thinks that HIV research should be de-funded and the money used for gay conversion therapy. Jesus Christ on a bike, let that sink in for a moment... but at least he actually won't be able to do that, thankfully.
Hillary was also a terrible option, she failed before and nobody really wanted her still. Even if she won her mandate wouldn't last, we all knew she had health problems and was trying her hardest to hide it from the public. Not to mention I completely found it irritating at how she kept claiming it was time for America to have a female president, at how they needed a woman in charge. Well I say this from across the pond, we had Margaret Thatcher and she was HORRIBLE, now we have Cruella de May in charge! It matters not what gender a person is, it matters what their policies are and whether they can run a country, but I digress. The safer options for the Democrats would've been to nominate Sanders. He would've given Trump a run for his money. (addendum, Larry Sanders, Bernies' brother tried to contest the Witney seat here as a Green Party candidate but lost, he was originally a member of the Labour Party under Tony Blair but left because of him.)
That being said, things aren't so great here. At least America went through the whole election process, Theresa May got in through the backdoor. Funny thing about that, back in 2007 she accused Gordon Brown not having the mandate to lead and demanded an election, now suddenly the tables have turned.
Now with Brexit, Trump's presidency and with more elections coming up in Europe, particularly the chance for Le Pen to win in France and Geert Wilders in The Netherlands, prospects are not that bright but at least these elections is one thing, it's a big middle finger to the established political elite.
