@CampaignDiaries hard to believe, but--on average--a single nyt/siena poll over the final three weeks has beaten an average of non-nyt/siena polls in the same races (though it's a close call) (fwiw i wouldn't use late RCP avg v. early poll for PA, and i wouldn't use RCP w GOP polls) — PolitiTweet.org
