Using the Generic Vote to Forecast the 2006 House and Senate Elections

Abstract

This article describes a model for forecasting the outcomes of congressional elections based on national political conditions and candidate behavior. Pre-election Gallup Poll data on the generic vote and presidential approval are used to measure national political conditions and data on open seats and challenger quality are used to measure the behavior of congressional candidates. The model is tested with data on U.S. House elections between 1946 and 2004. A simpler model based only on national political conditions is tested with data on U.S. Senate elections from the same period. The results indicate that Democrats have a good chance to regain control of the House of Representatives in November. Democratic gains are also likely in the Senate but it will be difficult for Democrats to pick up the six seats that they need to take control of the upper chamber because only 15 of the 33 seats up for election in 2006 are currently held by Republicans.
