"But Kenneth Fernandez, director of the North Carolina-based Elon University Poll, cautioned against making any quick decisions. "We’ve seen the lead changes in North Carolina a dozen times and results have almost always been within the margin of error. I don’t think you will see many well-funded polling organizations pulling out of North Carolina, Florida, or Virginia," he said.Pollster pulls out of Fla., NC and Va., says Obama can’t win there
Fernandez noted that pollsters with limited time and money might choose to focus on different states, but "it seems premature to make a methodological decision based on a single campaign event and poll change," he said.
Fernandez pointed to 1948, when Gallup stopped polling two weeks before the election and predicted that Thomas Dewey would defeat Harry Truman. "When you make such a decision with incomplete information, you are increasing your chances of being wrong, very wrong."
Other polling outlets said they would continue surveys in Virginia, North Carolina and Florida. Roanoke College plans more polling in Virginia, and the Marist Institute, which conducts polling for NBC and The Wall Street Journal, also will keep polling in all three states."
