Donald Trump first tried it out in 2016, at an August rally in Ohio. He said that perhaps he wouldn't accept the election results in his race against Hillary Clinton, that the election was "rigged." He then mentioned it at more rallies and even at one of the fall debates. He didn't have to challenge the result that year, but the stage was set. When he lost in 2020, he started the lie back up again and to devastating results: an insurrection at the Capitol in January 2021. In the more than five tumultuous, paradigm-shifting years of Donald Trump's presidency and beyond, his near-constant lying has become a fixture of political life. It is inextricably linked with how his party behaves, how the Democrats respond to it, and how he remains relevant, even after a decisive loss in 2020. Jonathan Lemire explores how this phenomenon shapes our politics. He uncovers that "The Big Lie," as it's been termed, isn't just about the 2020 election. It's become a political philosophy that has only further divided the two parties. Republicans are still wholly under Trump's sway. From his retirement at his Florida and New Jersey clubs he meets with Republican officials, aspiring candidates, and advisers and demands loyalty about this twisted way of thinking. And Democrats still deal with him as their opposition party is driven by a blatant lie. The parties aren't divided by the aisle-they're on different planets.
