The only issue will be if he would attract enough African-Americans votes in states like MI, WI, PA, NC, SC, GA, MO, MD, FL and TX
You chose some weird states to claim he needs the black vote. Aside from that I don't think Sanders is necessarily unpopular with black people. Clinton had real popularity with them last time around. And while I think Corey Booker might steal a good chunk of the black I think the fact that there will still probably be a crowded-ish primary on Super Tuesday erases some of that fact. Also don't think Booker will be nearly as popular with black voters as Obama was.
