For some context on the answer to this seeming contradiction read William Link’s thought-provoking biography of Jesse Helms, Righteous Warrior. Right-wing white supremacists are too valuable to conservatives in the political sense to risk alienating them from would-be conservative candidates. In fact the tale Link tells about election shenanigans and polling place tricks not to mention race-baiting as a last-minute tactic in political campaigns offers a cautionary reminder as we head into yet another close election. Thanks for pointing out this disparity in law-enforcement attention.
