My thought was that without a black person running, blacks are not going to make the effort to vote.
In CA some homo legislation was voted down because black people, notoriously anti-homo, came out in droves to vote for Barack and the homo legislation was on the ticket at the same time.
Prop 208 in 2008 that banned gay marriages in CA — and it is absolutely true that the HUGE turnout by african americans materially contributed to that initiative passing.
Sure, for 2016, the african american vote MIGHT not be as large as it was for Hussein. One of the reasons the usual suspects are screaming about how racist Donnie-boy is — trying to fire up the minority voters.
