In this article, we present a forecast of the 2010 midterm House election based on information available in early July 2010. We combine this forecast with a note of caution, explaining why electoral circumstances might lead our forecast to err. Finally, we present guidance regarding how to update the electoral forecast for 2010 based on new information that will become available leading up to Election Day.
