polling question: black voters?

[dougrhess]

I recall being told that black voters (maybe other non-whites, too?) tend to not say they are likely to vote until much later in the season. Is this true? If so, does this affect "likely voter" polls in any way?

Thanks. What do they weight the data to? Past voting patterns based on race, age and gender? Or to the population of citizens? Registeres citizens?

Oh, well, recent statewide elections would still be off by a large amount for minorities in some states, maybe most, compared to presidential years. No?
