Also Trump 2 proves without a doubt that at least half of the american voters are absolutely insane or incredibly stupid. For 1 there used to be some doubt.
We in Europe are enjoying roughly 15-20% insane/stupid ratings at this point, which is not great but still a bit better.
Anyone that doesn't agree with you politically is insane or stupid?
This logic applies if you believe it was an honest and fair election.
The algorithm/method of vote determines a large part of the political landscape (and in the US, only 2 significant political parties can realistically exist. People have to choose between those 2 and lot choose to abstain).
Other methods of vote exist, e.g. if https://en.wikipedia.org/wiki/Rated_voting was implemented I think the political landscape would be very different.
