Welcome to operation clean-up. A year ago Zuckerberg’s star was flying so high that there were rumours the 34-year-old might run for office. He and his wife, Priscilla Chan, 33, had even hired Barack Obama’s former campaign manager, David Plouffe, to lead the political advocacy team at the Chan Zuckerberg Initiative, their philanthropic organisation. They recruited Democratic pollster Joel Benenson as a consultant, and Zuckerberg embarked on a year-long ‘listening tour’ on which he travelled to about 30 of America’s 50 states — all of the states he hadn’t previously visited. The latter seemed very much like a try-out for hitting the campaign trail. Sure enough, he hired Charles Ommanney, a photographer for both the Bush and Obama presidential campaigns, to document his travels. Despite Zuckerberg’s denials (in a Facebook post, he wrote, "some of you have asked if this challenge means I’m running for public office. I’m not" ), rumours of ambitions for 2020 abounded.
