Wish I had the same optimism, Ms. Nina, but my senses sense a different take:
None of this will change Biden's lurch to the Right; in fact, Corporate will still spin this as "Biden massively beats back noncommitted effort, wins Michigan primary by bigger landslide than Obama"; and the pressure on liberal critics to bend the knee and succumb to "I hate Biden, but gotta vote for him anyway because Trump BAD".
And that effectively rewards Biden's rightward lurch.
