Que estaba pensando? De Blasio: “I learned from that mistake.”

After getting a drubbing from fellow Democrats after he quoted Che Guevara — apparently unknowingly — during a rally for Miami airport workers earlier today, New York City Mayor Bill De Blasio said he’s sorry.

During an interview shortly before 6:30 this evening , CNN’s Wolf Blitzer asked De Blasio where he picked up the Spanish-language phrase, “Hasta la victoria siempre,” which means “Until victory, always!”

“That’s an honest mistake and I do apologize for it,” De Blasio said, after Blitzer played a clip of De Blasio speaking the quote, which drew a loud roar of support from the striking airport workers at the rally.

“The folks there … took it as just an affirmation of the strike,” De Blasio explained. “I do apologize because I didn’t understand the context, and I certainly did not mean to offend anyone.”

But Blitzer pointed out that Che Guevara is a figure despised by many of the Cuban-Americans who populate Miami.

“I understand the sensitivities. I learned from that mistake,” De Blasio said.
