Slate agrees: publish everything.

This is from a Seattle Times article, quoting Jack Shafer:

Some critics believe the exit polls have become too proprietary. Instead of trying to keep the results secret, the poll results and methodology should be entirely above board, said Jack Shafer, the media critic for Slate, an online magazine that published leaked poll results on Tuesday. That way, he said, the public can be better informed about how to view poll results — and make a more informed decision about how to interpret them. "There is very little transparent about what they do," he said. "They are basically accountable to no one."
