The Ds HAVE to have the blacks turn out and vote for Hitler
y. If they don't turn out in huge numbers, the Ds will lose because they will lose PA, likely OH and MI, and possibly MD and NJ (take a look at the 2014 Gubernatorial election in MD where the blacks stayed home and the Rs won with a white, conservative businessman).
Their platform is overtly racist, pandering simply to one race, and it's becoming clear as day to those with their eyes open and heads not up their asses. It's also costing the Ds the support of the EMS, Fire, and Police unions.
Hitlery is simply hated, and they are trying desperately to overcome that.
