Really want to know? IMO having grown up in several "ghettos" around the country, it's because the Democrats became the Party of "give-ism." They take other people's money and give it to us. We could count on them excusing all of our faults as due to oppression, racism, and slavery. That and they offer us goodies in the form of free or near free HUD or section 8 housing, guaranteed incomes playing the welfare system if we have enough kids or can't find a job, free or near free college educations with head-of-the-line affirmative action programs while making special SJW jobs for us!!
Why not vote for them? Of course now they are trying to replace us with immigrants, so that's starting to rock our boat...
(All the above is sarcasm with a grain of truth)
