portland trail blazers play. this early day in the campaign, large crowds are at some level just an indicator of how excited people are about a candidate, as opposed to how broadly popular they are. but reminder. 20,000 people turned up in february 2007 in austin, texas, for a man by the name of barack obama. yesterday's rally for bernie sanders was the largest turnout for any 2016 presidential candidate thus far. also the first rally for sanders since revealing a new racial justice platform. and after facing protests from black activists the day before, the new public face of the sanders campaign yesterday, a young black political activist, simone sanders, prepped the crowd what to do in the face of other protests. >> if there happens to be a disruption tonight, i want everyone in this stadium to respond with a chant. can you all do that for me? i want you to respond with the chant "we stand together."
