That message has to be delivered by Black Conservatives. I've been working actively on political campaigns for years, and white Conservatives are not welcome in Black neighborhoods. Black Conservatives have a hard enough time, but whites get nowhere.
And getting Blacks from integrated neighborhoods to come out to hear Conservative candidates isn't easy, either. My neighborhood has about 20% Blacks, but they never account for more than about 1% of the audience at any Conservative rally.
That's not true. For instance, Tom DeLay can deliver his own message better than a surrogate.
