"The RAND Midterm Election Panel uses the American Life Panel (ALP) to study voting intentions, public opinion, and voter behavior. The ALP is a scientifically recruited Internet panel. Using the ALP allows us to contact the same people over time to study the evolution of their voting intentions, behavior, and opinions. Furthermore, we follow previous RAND election polling by asking respondents about their voting intentions in probabilistic terms (percent chance), which improves forecasts. This document provides a detailed description of our methodology.

In addition, the supplemental materials available as a PDF file in the upper-right of the page provide the specific survey questions and data tables discussed in posts on the RAND Blog. We will continue to post additional supplemental material as it becomes available throughout the fielding of the RAND Midterm Election Panel."
