The question is almost a year old, and not currently being asked in quite the feverish way it was over the summer. But let’s try it again: could Mark Zuckerberg run for US president? The founder, chairman and CEO of Facebook began 2017 by announcing his latest “challenge”: a pledge to visit the 30 US states he had never spent time in before, which has now been achieved. Along the way, he has made a point of meeting Trump voters, sampling the mood in post-industrial backwaters, and seeing at first hand evidence of his country’s opioid crisis. He now talks about the importance of community, and the need for his generation to find a collective sense of purpose, rather suggesting the leading actor in a school play about Bobby Kennedy.
