There is power in numbers. Starting in 2006, a consortium of 39 universities came together to create the Cooperative Congressional Election Study, the first truly large-scale academic survey project aimed at studying the midterm Congressional elections.

Even very low-… Read more about The Perils of Cherry Picking Low Frequency Events in Large Sample Surveys
