Generally speaking, people with higher discretionary incomes, who are more susceptible to advertising, tend to be liberal. Think of your New Yorkers, your Tech Bay area faggots. They have a ton of discretionary income, are urbanites, and typically appreciate having fags and niggers in their advertising. Conservatives in "Middle America" won't spend as much as quick, so why advertise to them. Better to advertise to their kids. But they are advertising because they are making money. Don't forget that.
