To save money this year, the [exit poll] consortium is doing bare-bones exit polling in 19 states. Enough voters will be questioned in those states to help predict the outcome of races, but not enough to draw narrative conclusions about the vote - what issues mattered most to women voting for Mitt Romney, for instance, or how many Catholics voted for Barack Obama.
The affected states are: Alaska, Arkansas, Delaware, Georgia, Hawaii, Idaho, Kentucky, Louisiana, Nebraska, North Dakota, Oklahoma, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia and Wyoming, along with the District of Columbia.
Each is considered a non-battleground state with polls showing a strong advantage for one of the presidential candidates.
