There were much bigger flaws than that. He never explained what correlated to what. He never explained what methodology he used to bucketize people into hardcore left/right, moderates, and swing.

Agreed, his presentation was D- at best. He saved it at the end with something we can actually dig (population growth vs. voter growth). Would need to compare to other western states to see how that data compares and correlates. Outliers would be extremely interesting and flag potential fraud.
