There's also an elitist wing of the Republican party that, if it doesn't dislike blacks, is scared of them. You're not going to get many votes in a district if you won't even show up in the neighborhood. Republicans will never be able to out-liberal the liberals in getting a percentage of the black vote, but I think there are many blacks who would vote Republican if they thought someone cared about their interests. This doesn't mean pushing a "black agenda" of quotas, welfare, and abortions. That plays to a black stereotype that's, if anything, more destructive than the Stepinfetchit characters common in old movies. It does mean acknowledging individuals as real live human beings and not simply demographics.
I think 30% is the breakover number, and I also think that's doable. At 30%, we start seeing black delegates at the conventions, signs in yards, and Rats seeing that the Jessie Jackson/Al Sharpton race-pimping is no longer working.
Here's the message I'd deliver: "Democrats want people broke, in projects and living on welfare because then they'll vote Democrat. We want people wealthy, in their own homes and working a good job because then they'll vote Republican."
That's not elitism, it's self preservation. In my city, Blacks who live in integrated neighborhoods are approached by Republicans, and in fact, many of them are Republicans.
But the majority Black neighborhoods are high crime areas, and even the middle class Blacks won't go there. There are major events there, but you won't find a few volunteers walking the street.
Those areas do have high turnouts on election day. All Dem votes, of course. And I can assure you that the Dem party didn't have volunteers working the streets prior to the election, either.
