The Effect of the Size of Voting Blocs on Incumbents' Roll‐Call Voting and the Asymmetric Polarization of Congress

Candidates face a trade‐off in the general election between taking a more‐moderate position that appeals to swing voters and a more‐extreme position that appeals to voters in the party's base. The threat of abstention by voters in the party's base if their candidate takes a position too moderate for them moves candidates to take more‐extreme positions. I discuss hypotheses regarding how this trade‐off affects candidate positioning and describe my tests of those hypotheses using data on House members in the 107th Congress and Senate members for the period 1982–2004. I then present data on how the distribution of voters in the electorate has changed over the past three decades and discuss how, in light of my empirical findings, these changes might explain the observed pattern of asymmetric polarization in Congress in recent decades.     

Do young female candidates face double barriers or an outgroup advantage? The case of the European Parliament

While intersectionality is a recurrent theme in the literature on women's political representation, few studies empirically disentangle who are the women who get elected to parliaments. An argument on biases in recruitment practices suggests that those who are members of more than one outgroup, such as young women, benefit from an ‘outgroup advantage’. In elections, a candidate with two outgroup features might attract more voter support than a candidate with just one outgroup feature. Hence, nominating a candidate that is both young and female could be a rational move by (male) elites in political parties that allows them to open fewer seats to newcomers. These expectations are tested on data for all members of the European Parliament since 1979. Not only is it found that women's presence increased steadily throughout the parliament's history, but also that women's representation is consistently highest among the group of young representatives, lower among middle-aged Members of the European Parliament and lowest among older representatives.     

DEVELOPMENTAL TRAJECTORY GROUPS: FACT OR A USEFUL STATISTICAL FICTION?*

A rapidly growing literature in criminology and psychology uses a group‐based methodology to identify and analyze developmental trajectories. Some confusion has arisen about the interpretation of this novel statistical model and with it some degree of cautionary commentary. We begin with a discussion of the role of trajectory groups as a statistical device for approximating population differences in developmental trajectories. We then discuss three misconceptions about group‐based trajectory modeling that stem from misunderstandings about the approximating role of trajectory groups: (1) individuals actually belong to a trajectory group, (2) the number of trajectory groups is immutable, and (3) the trajectories of group members follow the group‐level trajectory in lock step. We also point out that groupbased statistical modeling is not bound at the hip to the testing of taxonomic theories, and can just as well be used to test nontaxonomic theories.     

What Happens When House Members “Run with Congress”? The Electoral Consequences of Institutional Loyalty

This article characterizes the electoral consequences of messages of institutional loyalty and disloyalty sent by incumbent House members to their constituents. We show that, for the contemporary House, there is variation in these messages—not all incumbents in the contemporary House “run for Congress by running against Congress.” Moreover, we show that these messages can, under the right conditions, have significant electoral consequences, even after controlling for party affiliation and district political factors. In addition to demonstrating the electoral relevance of legislators' presentations, our results show an incumbent‐level link between constituents' trust in government and their voting behavior—a link created by interaction between constituents' perceptions, legislators' party affiliations, and the messages that legislators send to their constituents.
