The black community is far more likely to vote for a black man from Newark New Jersey than they are to vote for a San Francisco liberal woman who questioned the CIA director about gay rights.
If Booker runs then he will pretty much destroy any chance Harris has of being the nominee.
Doubt that matters. At this point what people associate Harris with is her questioning of Jeff Sessions. Which, considering Sessions history didnt exactly play badly in the black community..
Booker also testified against Sessions.
