BLM is clearly not picking sides in the Democratic race for President. Bernie Sanders has been interrupted more than once by Black Lives Matter activists, and the leadership in the movement has refused to endorse a candidate for 2016.

Huffpo:

[BLM Activist] Ashley Williams demanded that the Democratic presidential candidate account for inconsistencies in her record on race, specifically around comments she made about crime in 1996.

...As Clinton spoke to the crowd, Williams stood to her side and held a sign quoting controversial statements Clinton made in 1996 in reference to at-risk youth, when she said "we have to bring them to heel."

"I wanted to bring her to confront her own words," Williams told The Huffington Post after the protest, adding, "We did this because we wanted to make sure that black people are paying attention to her record, and we want to know what Hillary we are getting."

The demonstration comes three days before the South Carolina primary, where turnout from black voters will be key to Clinton clinching the Democratic nomination.
