Um, guys?

Are Kurtz and Kaus really this ignorant? They're asking why polling organizations only compare their new polls to their own old polls, I think. But it's hard to be sure because it's such brain-dead basic reason: polls differ in their methodology. Therefore, two polls by different organizations that span the same time period may yield different results for reasons other than natural fluctuation within the margin of error. They really will reach for every last inch of lift to put under Dear Leader's shoes.
