If a week is a long time in politics, the past decade has felt like a lifetime. A series of explosive revolts has erupted around the world, redrawing the political map and amplifying the already deafening online echo chambers. Sometimes it feels like we've lost all common ground. Sometimes it feels like politics has stopped working. Sometimes it all feels too much.But what's behind the unrelenting upheaval? Is there more to it than what we're usually told about crumbling elites and a shrinking centre ground? How did everything get so polarised - so frenzied? And why does there seem to be a revolving door between high office and reality TV? Look no further than fandom - the hidden power behind many of the most surprising events in recent history... and the key to getting to grips with them. From the mass movements resulting in Brexit and Trump, culture wars and conspiracy theories, to online engagement that enriches lives and inspires positive social and political change, I Heart Politics reveals how a passionate wave of people power is upending our politics and remaking the wider world.
