Their entire convention and platform will be an exercise in anti-white racism. Their constituent racial grievance groups demand it. It's all they have left - they have to finish kicking whites out of their party to keep all of the other factions happy. Trump is saying "Thank you!' and inviting white voters to come with him and follow his "dark vision." :)
If they drive whites out of their party they’d do well to consider it only takes 70% of the white vote to make a landslide in any national election.
