In the big cities, who votes Republican?

[opebo]

In black areas - no one.  Really.  Blacks typically talk a whole lot less politics than you might think, and tend to view whites as one whole group, regardless of whether whites are liberal or conservative.

Pretty accurate way to view them, really.

In white, ethnic/conservative areas, they aren't the minority.  Well, not at the national level - local level, yes.

You mean like Staten Island and the more intensely racist parts of Brooklyn, etc.?
