In the 2005 Doctor Who Christmas special, the British prime minister – an older woman called Harriet Jones – reneges on a promise to let a bunch of aliens leave the planet in peace. After she orders their ship to be shot down, David Tennant’s furious Time Lord tells her that he could bring down her government with a word – or, rather, six words. As she stands defiantly in front of him, he goes to her closest aide and whispers: “Don’t you think she looks tired?”
For the past few months, the “alt right” – a loose collection of bloggers, websites, internet wing nuts and other Trump-supporting flotsam – has been attempting a similar trick on Hillary Clinton. In 2012, the Democratic presidential nominee hit her head, and since then rumours have swirled about a more serious health problem. With appalling timing, the Clinton campaign finally responded to these rumours last week, only for their visibly sick candidate to need bundling out of a 9/11 memorial event on Sunday into a waiting people carrier.
