DJ--I atpaecirpe your analysis.I was shocked to discover that the rate of refusal is so high (80% or more).Can you direct me to a post here where you explain the methodology the pollsters use to compensate for the high rates of refusal?And isn't it likely that this year is going to exacerbate the problem? I think there's a huge gap in rate of refusal between Obama supporters and McCain supporters.Do you have current rate of refusals for the major pollsters?
