It's when I gave up on US politics. If only it was such that Hillary won... and not that DNC actively conspired to make that happen.
As messed up and anti-democratic so many things are in the US leading to "pick one of two things". The whole system is fundamentally broken when the selection of those two things is corrupt.
But... when a person I wouldn't trust to be mentally suited to pack a bag of groceries* or park a car*, is elected president, and gets to pick several supreme court justices... The world isn't laughing at the US. They were laughing at the thought of Trump being in he primaries. They're deeply concern that a complete fuckwit ended up in charge, and what that might lead to.
Democracy (i.e. the system of governance) requires informed voters. GOP (the political party) requires uninformed voters.
The only way you can vote Republican or think that the orange baboon can be entrusted with anything more important than throw feces, is one of two thing (or both): 1) you are an idiot / uninformed 2) you are morally corrupt
*: this isn't a put down directed at people who do these things, but that it requires some mental function in order to not crash the car, or steal some groceries... and I would be equally comfortable with Trump in that regard, as with a 6 year old. Which is to say: not at all. Which puts in perspective what I think of him being president.
