So, why did Biden said this?

[Colobo]

BIDEN: The Washington Post: "After a lengthy critique of Bush administration education policies, Biden attempted to explain why some schools perform better than others -- in Iowa, for instance, compared with the District. ‘There's less than 1 percent of the population of Iowa that is African American. There is probably less than 4 or 5 percent that are minorities. What is in Washington? So look, it goes back to what you start off with, what you're dealing with,’ Biden said. He went on to discuss the importance of parental involvement in reading to children and how "half this education gap exists before the kid steps foot in the classroom."

The Biden campaign moved quickly to clarify the senator's remarks in a statement: "This was not a race-based distinction, but a discussion of the problems kids face who don't have the same socio-economic support system (and all that implies -- nutrition, pre K, etc.) entering grade school and the impact of those disadvantages on outcomes."

Nice spin, Joe. However, it's not the first time you make that "kind" of remarks...
