The best pollsters were very hesitant about Clinton's lead.
There is no arrogance on the left, because the real left were out of the election as soon as Clinton was nominated.
Clinton was a centre-right corporate insider candidate. Trump was a far-right corporate outsider candidate. Neither has any genuine interest in working Americans.
The election was a farce because the only two candidates were crooks - Trump certainly, with his appalling record of failing to pay contractors and his likely mafia ties, and Clinton because of all the emails in WikiLeaks, at least some of which may be genuine.
The only people who will benefit from Trump in the short term are the 1% who will receive some generous tax cuts. In the long term, it's quite likely - or at least a serious possibility - that no one at all will benefit.
So - stop the crowing please. This isn't a sports game, and Trump's election isn't a touch down. The reality is the stadium is on fire, the crowd are about to start panicking, and there's an earthquake and a hurricane on the way.
