I agree with Carville that anointing a replacement is a bad idea. An open contest is a better idea. Here's a gift link to Carville's guest essay in the NYT. https://www.nytimes.com/2024/07/08/opinion/biden-democratic-nominee.html?unlocked_article_code=1.500.afTP.mvE9-IJ7fTYj

I still think Biden should have the opportunity to be part of the open contest and that he should release his delegates and keep his hat in the ring, if he wants to. To me it gives him a dignified exit without a surrender. https://medium.com/@marcus17043/an-outside-the-box-suggestion-for-biden-6c336f4a9908
