I heard talk that she may want to get into politics. The obvious difference between her speech and Dean is that when Dean went off the rails, he was already running for president.
I heard a sound bite of her speech, and it sounded like it may have gone over okay at an actual convention, with a large number of people attending. Given the setting forced on us by covid, maybe a speech like she gave would prevent any campaign of hers from even getting on the rails.
