Alexandria Ocasio-Cortez held a livestream case-making tutorial on her social media channels yesterday to teach her supporters how to argue using evidence and logic.

The 2 hour tutorial was designed to help her followers practice building a strong argument for their chosen political stances. To demonstrate by example, Ocasio-Cortez went through a series of mini lectures, drawing on many examples from history, politics, and literature. Her target audience was primarily left-leaning, yet Ocasio-Cortez also emphasized the importance of understanding and rebutting other people’s positions. In response to the tutorial, supporters flocked to the comments section to thank Ocaso-Cortez for the new skills they had gained. “Now I know how to explain the Green New Deal to people who don’t understand the urgent necessity of its implementation,” one excited student wrote.
