 Biden has the delegates who are bound to vote for him by those very rules to deliver the nomination on the first ballot. And to Ocasio-Cortez's point, there is no clear answer to what happens if Biden drops out. She is right. It would likely be a chaotic process, potentially one that further divides Democrats and undermines the whole party going into November. So what is so amazing about this moment is that so many Democrats are willing to say that's a risk they're willing to take.
