Inspired by Donald Trump’s election lies, a growing movement of grassroots activists mobilized around the country to pick up where the insurrection left off, laying the groundwork to succeed next time where Trump had failed to keep himself in power. But their own success in taking over and purging the Republican Party became their undoing. Still, the MAGA Republicans proved uninterested in learning from that defeat, only becoming more extreme, divisive, and dead set on returning Trump to power. Washington Post national political reporter Isaac Arnsdorf has spent years at the forefront of reporting on this growing movement. Drawing on extensive, exclusive on-the-ground reporting around the country, and deepened by historical context, Arnsdorf has produced the defining journalistic account of the origins, evolution and future of the MAGA movement.
