Barney Frank's Lessons for BLM etc.

Barney Frank in his memoir Frank talks about effective politics, using the National Rifle Association as an example.  He wrote the book before the Black Lives Matter organization/movement came into being, but I'd apply his lessons, as I recall them, to BLM. Important things:

• having supporters in many congressional districts.
• having specific "asks"--something the representative can do.
• keeping rhetoric and congruent--don't take positions or make threats you can't back up.
• build a reputation.
• pick your spots to demonstrate your power.
