This week, the Democratic Party presented its first-ever virtual nominating Convention. Over three nights, a host of speakers—from establishment Democrats like Hillary Clinton and Michelle Obama, to progressive figures like Bernie Sanders and Alexandria Ocasio-Cortez, to moderate Republicans like John Kasich and Colin Powell—promoted a big-tent movement to defeat Donald Trump in November. John Cassidy joins Eric Lach to discuss what the Democratic Convention tells us about the general election, and what to look forward to from the Republican Convention next week.
