The so-called ‘Big Lie’, the idea that Donald Trump actually won the 2020 election and that there was a major conspiracy to steal the election and give it to Joe Biden, is so preposterous that one has to be delusional to give it any credence. And yet, it seems like many Republicans have bought into it.

The excellent investigative journalism outfit ProPublica has combined with the PBS program Frontline to produce an absorbing 53-minute documentary in which correspondent A. C. Thompson (who has previously investigated hate groups) tracks down the origins of the Big Lie, the people behind it, and their goal of trying to rig future elections to get the results they want. Although I have been following this story closely, I learned a lot of new things about it.
