I also have several entries in the incredibly useful Encyclopedia of U.S. Campaigns, Elections, and Electoral Behavior, edited by Kenneth F. Warren and published by Sage Publications.

We examine various measures of ideology and find that nominal measures are more appropriate for U.S. Courts of Appeals judges.


In the context of religious free exercise cases, we find that failure to account for the decision of losing parties to petition leads to incorrect estimates in models predicting the granting of certiorari.

This work examines the partisan realignment of the 1930s, presenting evidence that the growth in Democratic support might not have lasted if not for World War II and post-war economic growth.



We question the existence of a sizable casualty effect, finding that events that signal the potential success of the war effort had far greater effects on presidential approval during the wars in Korea and Vietnam.

This research finds that members secure more benefits when they have voted more often with their party leaders and have donated to the campaigns of their co-partisans. The findings suggest that the pork barrel is an important tool that party leaders use to encourage behavior supportive of the party.


We look at several surveys over a long period and find that the higher scores of men on political knowledge "tests" are due primarily to the increased proposenity of men to guess and women to respond "Don't Know."

Using suggestions from the post-mortem discussions of the 2000 election forecasts, we estimate many different forecasting models and find that the adjustments suggested by a number of authors do not produce better forecasting models.
