From the other side of the Atlantic, two things strike me right now: The Republican double standard over the nomination for the Supreme Court and Trump's comments about electoral fraud if he loses.
Firstly, to tell Obama he couldn't nominate several months before the election, but four years on insist Trump can, is breathtakingly dishonest. Republicans should be ashamed to go down this road.
Secondly, Trumps' claim of forthcoming voter fraud, sans evidence, whilst simultaneously allowing Republican states to attempt to gerrymander the election through voter suppression, is an attempt to undermine democracy itself. I seriously fear for my friends in the US, of whatever political persuasion. I foresee violence ahead. Keep safe, folks.
