While I disagree at some level with most of what you've written, I think the most egregious point is that nothing that you wrote is linked to the conclusion you draw.
1) There are reasons other than white nationalism for political parties to play politics with voting laws. It is overwhelmingly likely that these changes target Democrat voters rather than minority voters.
2) If this is the best a party of white nationalists can manage - marginal changes to try and tip tight elections in their favour - then the situation seems to seem very much under control from the perspective of all the non-white non-nationalists. It is hardly a defining policy.
