The white vote is not irrelevent because they can be the swing vote and that way exert tremendous power. The DA must become a black party  to stand a change in winning in 2019.  The image of the DA must be of an ANC but without the corruption and poor governance. They need to offer the same populist promises to the electorate and more. HZ needs to form a new party for the white voters. Racial politics is the only winning politics is SA.
