Most blacks are working people and taxpayers, who are not benefiting from the welfare state programs of the Democrats or from affirmative action. Many live in places where they are more likely than whites to become victims of the violent criminals that liberal judges turn loose and liberal governors pardon. Blacks are also more likely to gain from vouchers that would enable them to pull their children out of failing public schools and give them a chance to get a decent education in a safer environment. Democrats cannot give them that because of the enormous influence of the teachers' unions within the Democratic party. Since the teachers' unions contribute millions of dollars to the Democrats, only Republicans are free to support vouchers.
Violent crime is another social problem that hits blacks especially hard.
In some years, there are more blacks than whites murdered in absolute numbers. However, even in high-crime neighborhoods, most people are not criminals, but are more likely to be victims of crime. That is especially true of black ghettos. Nothing has a proven track record of preventing crime like locking up criminals. Gun control laws do not actually control guns.
