If you want to blame groups for a Biden loss then blame all those 2020 moderate Trump voters who still are sticking with Trump. Biden knifed many of his constituent groups in his shift to the right. And the polls in swing states are still as bad as they’ve ever been for Biden.
I highly recommend this podcast. He does a great job of differentiating what the different authors say and what are his own opinions. And he adds corrections to the episode when listeners point out his mistakes. The French, Haitian, 1848, and Russian revolutions really changed how I see the world. Be warned, they can hit dozens of episodes each.
The American and English civil war are OK, not Duncan’s fault, it’s just the non Anglo revolutions were better material IMO.
