Trump may or may not be a good president, his victory speech is the most calm and respectable he's looked. In the very least he has a far easier ride to surprising people in a positive fashion than he does in a negative way.
However, Trump's campaign was negative, misinforming, lacking in policy (the policy there was was scary - deny climate change and repeal Obamacare) and often reduced his "movement" to three or four word slogans which didn't really mean anything.
The best thing Hilary did was release a video which showed all the clips of Trump's racist, homophobic, sexist, ignorant and crass comments with the tagline "our children are watching". Sadly, it's not just American children watching but also hundred's of other political minds who see that you can run such a campaign and still be rewarded with victory. We already have "dead cat" Crosby with a Queen's honour and now Trump with the biggest job in the Western world.
It's not just the next four years which could be very scary (again, he may surprise us all) but the countless campaigns further down the road which will borrow from Crosby and Trump and be rewarded is a terrifying prospect.
