From the liberal think tank Center for American Progress, an e-mail on Ted Kennedy’s statement that “Judge Alito has not written one single opinion on the merits in favor of a person of color alleging race discrimination on the job.” “The operative word here is ‘written,’” the e-mail says. So it appears that the Kennedy argument is not that Alito has not voted in favor of minority rights in cases of persons of color alleging race discrimination on the job — Republicans have cited four cases in which that happened — but that he has not written those opinions.
