Captive constituancy
The Democratic party's bread and butter.
Notice how they only address the concerns of african americans, the elderly, the poor ect come election time? That's because they're confident most of their "protected classes" have nowhere else to go.
Ever notice most of the Democrat elite are white? Yeah, a black person gets to be mayor, but look higher and it looks pretty whitewashed.
That's no accident.. Democrats don't care about you, they care about the vote. The only way to MAKE them care is to vote Republican, in mass numbers, which will never happen, which makes you a captive constituancy and means they really don't need to do much to get your vote.
