Gore is just continuing the politics of divisiveness which has worked so well for the Democrat power brokers. The goal is to keep blacks outraged by lying about the policies of conservatives.
The strategy is reinforced by black leaders and keeps blacks voting 90+% Democrat.
I only see a switch in the strategy when and if the GOP makes inroads into the Latino community because if the GOP wins over even a third of the Latino community, even if Democrats get 100% of the black vote, it won't amount to victory.
