Networks, AP cancel exit polls in 19 states

Dan Merkle, director of elections for ABC News, and a member of the consortium that runs the exit poll, confirmed the shift Wednesday. The aim, he said, “is to still deliver a quality product in the most important states,” in the face of mounting survey costs.
The decision by the National Election Pool — a joint venture of the major television networks and The Associated Press — is sure to cause some pain to election watchers across the country. (For a full list of the states that won’t have exit polls scroll to the bottom of this post.)
Voters in the excluded states will still be interviewed as part of a national exit poll, but state-level estimates of the partisan, age or racial makeups of electorates won’t be available as they have been since 1992. The lack of data may hamper election night analyses in some states, and it will almost certainly limit post-election research for years to come.
