Donald Trump is a child who holds a man's job. That any right-thinking person could have voted for him in 2016 is baffling. That people would consider doing so again is stunning - it is unimaginable that any person who votes for Mr. Trump (in 2020) is not doing so as an act of pure spite. As of January 2017, I consider myself lucky to not be an American (although he can still do damage beyond American borders, not least here in Canada).
Having said this, it is astonishing that Joe Biden is the best the Democrats can come up with.
