Given my background, the earliest case I can think of is: https://news.ycombinator.com/item?id=38314926 https://news.ycombinator.com/item?id=38314926 Besides his advances in polling techniques, he also "argued that political campaigns must adapt themselves to public opinion, which he characterized as a 'moving picture of sentiment.'
