For the first time in over two decades, we will not have individual exit polls from all 50 states:
http://www.washingtonpost.com/blogs/the-fix/wp/2012/10/04/networks-ap-cancel-exit-polls-in-19-states/In order to cut costs, the networks will have exit polls for 31 states, but will not do the following non-competitive states:
They're also going to reduce the number of states for which they supplement the in-person polling with telephone polls to catch early voters to just 15 states.
To be clear, it looks like there will still be some individual precincts polled in the states that are "skipped", with results to be included in their national exit poll, and the focus will be on the national exit poll. But they won't be sampling enough precincts in those 19 states to produce individual exit polls for those states. (For example, they might poll one or two precincts in North Dakota to include in the national poll, but one precinct isn't good enough to produce a separate poll for North Dakota.)
