Huges, Laura (24 February 2016). "Tony Blair admits he can't understand the popularity of Jeremy Corbyn and Bernie Sanders". The Daily Telegraph. Retrieved 14 May 2019. "In a joint Guardian and Financial Times interview, Mr Blair said he believed some of Mr Sanders' and Mr Corbyn's success was due to the "loss of faith in that strong, centrist progressive position", which defined his own career. He said: "One of the strangest things about politics at the moment – and I really mean it when I say I'm not sure I fully understand politics right now, which is an odd thing to say, having spent my life in it – is when you put the question of electability as a factor in your decision to nominate a leader, it's how small the numbers are that this is the decisive factor. That sounds curious to me."

After decades of dormancy verging on death, it is rising again in the westIn the UK, Jeremy Corbyn just led the Labour party to its largest increase in vote share since 1945 on the strength of its most radical manifesto in decades. In France, the leftist Jean-Luc Melenchon recently came within two percentage points of breaking into the second round of the presidential election. And in the US, the country's most famous socialist – Bernie Sanders – is now its most popular politician. [...] For the resurgent left, an essential spark is social media. In fact, it's one of the most crucial and least understood catalysts of contemporary socialism. Since the networked uprisings of 2011 – the year of the Arab spring, Occupy Wall Street and the Spanish indignados – we've seen how social media can rapidly bring masses of people into the streets. But social media isn't just a tool for mobilizing people. It's also a tool for politicizing them."
