The radio ad aired by one of Obama's labor allies re-injects ethnicity into the Democratic primary contest in sharp terms.
"Hillary Clinton does not respect our people," the ad says in Spanish (original and Clinton campaign translation after the jump), referring to the lawsuit that failed today to shut down special caucus sites on Las Vegas' strip. "Hillary Clinton is shameless."
"Sen. Obama is defending our right to vote. Sen. Obama wants our votes. He respects our votes, our community, and our people. Sen. Obama's campaign slogan is 'Si Se Puede.' Vote for a president who respects us, and who respects our right to vote," the ad says, according to a transcript provided by the Clinton campaign and confirmed in part by a union official.
