Not necessarily the best short-term news:
What would happen if an agreement were announced today that there would be re-votes in Florida and Michigan? Immediately, the previous primaries in those states would become dead letters. Instead of being 200,000 votes down in the popular vote (by her campaign's count), or 500,000 down (by my count, which gives Clinton her Florida votes), Clinton would be down in the popular vote by almost 1 million. And 193 delegates that they are currently counting would suddenly disappear.
