"I wonder if "culture" -- rather than being born Caucasian and with a silver spoon in your mouth -- would be your preferred explanation for why you're a multi-millionaire, while Latinos and African Americans struggle to make ends meet."
"The Olympics gaffe was just that. This comment is something more - a haughty misunderstanding of the real conditions, suffering, and history of peoples and regions. Basing foreign policy on the assumptions Mr. Romney exposed within himself would be unconscionable and dangerous."
