It is a favorite head-shaker among conservatives to wonder why black voters remain so in thrall to the Democratic Party, even though there are reasons they might be more comfortable with Republicans. The cry and moan goes up: The Democrats keep promising to be on their side and then screwing them over. Why can't they see?
Probably for the same reason that small-government conservatives keep voting for Republicans, despite their poor record of actually shrinking government. At least they say the right things, and some of them even do it.
We actually understand each other very well, when you think of it.
