Bolsonaro, Orbán, Salvini... Are our democracies in danger?

In Brazil, a nostalgic dictator at the gates of the presidency. In Hungary, freedoms trampled underfoot. In Turkey, a worrying drift towards authoritarianism. In Italy, the hard line in power. And then Donald Trump and Vladimir Putin... So many strongmen challenging the foundations of the rule of law. Authoritarian temptation seems to be global. So, are our democracies in danger?
