How likely are those people to vote Republican though? If there is little change of that then introducing a harsh new law might win more votes than it would lose.
How is it a "narrative"? The widespread and coordinated use
of drug laws to persecute minorities is a matter of historical fact. Are you disputing the historical facts? Are you familiar with the rigorous academic research on this subject? You might want to start here [1]. Calling something a "narrative" doesn't actually change anything, let alone the facts.
You say "drug laws" but then link to stories about marijuana. If you want to discuss historical fact, you can't just focus on marijuana when the picture is much bigger. African-American leaders[1][2][3] quite often wanted tougher laws about drug use. Drug laws may have been influenced in part by racism, but that is assuredly not the whole story. Black people don't want their communities destroyed by drugs and crime any more than anyone else, and they want enforcement as much as anyone.
