"I don't quite understand why Hillary is so despised in the US"
Because she and Bill skirt the law and it certainly LOOKS like The Clinton Foundation is a political money laundering apparatus. She becomes SoS and then BOOM. Her and Bill's speaking fees skyrocket -- by people donating to the Clinton Foundation. And many of those donors end up getting lucrative contracts. BTW, there's an investigation on-going on the Clinton Foundation.
The email issue is another example. It appears the sole function of her private server (which suffered from known security issues as late as early this year) was to allow her to skirt FOI requests. Vanishing emails, completely destroyed hard drives, unusual immunity deals for employees...
These are just two of the recent LARGE issues. Benghazi? Claiming publicly that it was due to some youtube video while we now now (because of now found previously deleted emails) was known to be completely unrelated. Ignoring multiple requests from the ambassador's office in Benghazi for increased security is another concern... It smells really bad.
You can go back to the 70's and 80's with the Whitewater real estate scandal which had several people placed in prison while the Clintons remained completely untouched. Then in Bill's "12th hour" as President, just before leaving office grants pardons to many of those found guilty. Why? It has the APPEARANCE of "dont say anything about Hillary and before I leave I'll wipe your record clean". It also smells really bad. Especially when you look at many of the other pardon's by Clinton before he left office.
There's a ton of stuff in between. Yes -- nothing that can get a "conviction" against them in court but enough "smoke" to tell any reasonable voter to make sure they never hold public office.
More than half the country do not like her and do not trust her. A huge number literally hate her. That's not a good candidate for leader.
"Even if I didn't like her, I would have supported her to prevent Trump. There's just too much at stake, like the possibly 4 (I think) supreme court judges to nominate. It's a disaster that this will fall into Trumps hands."
I can't get behind the idea of voting for "A" because they are not "B" rather than voting for "A" because I think "A" is a good candidate. Luckily, I live in California -- where they was no way Trump would win. Were it others, I would have had a much harder time deciding not to vote for either.
With regards to SCOTUS -- I fall on the side of liking conservative justices. They tend not to find "magic rights" that never existed before. The reason why I find that idea horrific is that if rights can "magically appears" they can also "magically vanish". The Kelo decision should be a particularly frightening example -- and it was all 4 of the liberal justices who made that choice with Kennedy (50/50) falling with them.
This is why it's so hard getting justices through the Senate now -- because we're not looking at their qualifications any more -- we're looking at their POLITICAL VIEWS to make their voter base happy. I blame the unintended consequences of the 17th amendment for that -- the Senate should be appointed by the various states and not popularly elected (changed by the 17th). They aren't SUPPOSED to be beholden to the people -- that's the job of the House.
There's an incredible balancing act our founders created to protect freedom and liberty. Democracy was feared by them but they used it to help protect against a tyranny by an over zealous government -- and they used a republican (little r) form of government with our three branches of government as a balance against a tyranny of the majority.
