The Role of Ideology in State Legislative Elections

Abstract

In this article, I examine the effect of incumbent ideology on elections in 45 state legislatures, showing that ideological extremists are more likely to be opposed in the general election than are moderates and that extremists tend to do worse in challenged elections than moderates do. I also explore the intervening role of legislative professionalism, finding that in the majority of state legislatures moderation is rewarded, though in the most professionalized legislatures, incumbents are actually rewarded for extremism. These results show that despite the informational disadvantage of the electorate, the ideology of state legislators is an important factor in elections.
