No surprise here. Axelrod is a pro. Political professionals may be evil, wrong-headed on policy, and ideological blinded (check on all three in this case), but they are not stupid about their profession. Axelrod knows that 9% response-rate polls, not matter how large the sample size, are unreliable and that polls that need to be weighted to get decent demographic balance are only are reliable as the assumptions in the weights even with an adequate response rate.
now, he has a problem with the polls. he was fine with them when they were wildly inaccurate and biased in his favor.
