Marc offers a preview of the meeting on the 31st:
Almost certainly, Hillary Clinton will be disappointed at the results. But there won’t be much sympathy for her. She will have succeeded in changing the total number of delegates needed to reach the nomination, and she will have been awarded MORE NET delegtes then she received organically from her victory in a state like Ohio. She may threaten to protest the RBC’s decision to the rules and bylaws committee, but I doubt that her supporters will stomach a credentials fight.
And The Page reports DNC lawyers wrote a memo saying that Michigan and Florida can’t be fully seated.
