In this radio interview with Fox News' John Gibson (Feb 27, 2008), former democratic vice presidential nominee Geraldine Ferraro first plays the race card, in public anyway, which has caused a shitstorm this week. Ferraro rails against democrats who've sided with Barack Obama, saving special scorn for Georgia congressman and erstwhile Hillary Clinton supporter John Lewis, Connecticut Senator Chris Dodd, and rather oddly Connecticut congresswoman Rosa DeLauro, who apparently only supports Obama because her constituents are black.
You can hear this part about 3min into the interview.
