Ray Fair has posted his first forecast of the outcome of the 2010 mid-term elections. The dependent variable is not the number of seats but the percent of the two-party House vote going to the Democrats.
Bafumi, Erikson, and Wlezien have a paper, "Ideological Balancing, Generic Polls and Midterm Elections" forthcoming at the Journal of Politics.
