When DailyKos publisher and owner Markos Moulitsas demanded that his pollster produce raw data from the polls Moulitsas purchased, he established a principle of election polling transparency that could open up the checkered history of presidential elections in the United States.
The controversy erupted when Moulitsas (kos) fired his polling company. He was unhappy with their results and demanded that his pollster, Research 2000 (R2000), turn over raw data for review. Moulitsas said:
"Early in this process, I asked for and they offered to provide us with their raw data for independent analysis -- which could potentially exculpate them. That was two weeks ago, and despite repeated promises to provide us that data, Research 2000 ultimately refused to do so." kos
