How angry does is Holder and Obama about Arizona voting out Affirmative Action last night?

With 96 percent of voting precincts reporting, the Arizona Civil Rights Initiative — which will ban discrimination and preferential treatment on the basis of race, ethnicity, and sex by state and local government in contracting, employment, and education (including public university admissions) — is passing with 60 percent of the vote. Congratulations to Ward Connerly, Jennifer Gratz, Clint Bolick, and all the others who fought so hard for this measure over the past several years.

Arizona joins California, Washington, Michigan, and Nebraska in banning this kind of “affirmative action,” and Arizona’s voters did so by the largest margin yet.

Here’s hoping still more states will follow suit. In addition, remaining affirmative-action programs in other places are now more vulnerable to legal challenges. For example, it will be more difficult for universities to claim a necessity for using racial and ethnic admission preferences when public universities in so many states have eschewed them without the sky falling.
