Suggestion to blm: why don't you offer a list of actions and commitments...

...which, if agreed to by a particular campaign, will stop that campaign's events from being disrupted by your group and establish that the candidate in question has proved him or herself trustworthy?

This could even mean an agreement to let blm speak at the beginning at all events, and a public declaration that the candidate backed an action plan giving its agenda much greater nationwide prominence.

Anyone who is running for the Democratic nomination would likely agree to whatever you asked, and you'd have a list of things to hold them to after the election. It would be win-win and you'd have huge clout in the next administration, whoever led it.
