Did you read your own link? It says that affirmative action enjoys at least plurality if not majority support:
> Americans who had heard the phrase affirmative action in the Center’s December survey were asked whether they saw it as a good or a bad thing. Among those who had ever heard the term, 36% said affirmative action is a good thing, 29% said it is a bad thing and a third weren’t sure.
> By comparison, Gallup has asked U.S. adults whether they “generally favor or oppose affirmative action programs for racial minorities.” In 2021, the last time Gallup asked this question, a 62% majority of Americans favored such programs.
