Legislative advocacy in the early to mid-1980s in the California statehouse was the genesis for our Western Political Quarterly article (Thomas and Welch 1991) on the impact of women in legislatures. On behalf of California NOW and CARAL (the California affiliate of NARAL), Sue Thomas lobbied the 120 legislators on women's issues. At the time, there were just 15 women in the statehouse, 12 in the assembly and 3 in the Senate. Thomas and her colleagues frequently conjectured that the work might proceed more smoothly were more women legislators.1 And so, moving on to graduate school, she asked Susan Welch to help her craft research that would take that hunch and turn it into systematic research. With support from the National Science Foundation and the Center for American Women and Politics at Rutgers, we surveyed legislators in twelve states in 1988 to update decade-old or older research comparing women's and men's legislative activity levels and to extend that research to see if women made a difference in legislative policy. At the time, there had not been a lot of research on what women did they were elected to office, but what was available indicated that they were less active than men in a variety of legislative work, such as speaking in committees and on the floor, meeting with lobbyists (of particular interest given Sue's background), engaging in legislative bargaining, introducing bills, and passing legislation. In our work, we hypothesized that growing levels of experience and larger numbers of women would result in their increased confidence and participation. We also hypothesized that disparate, gender-based life experiences would result in greater sensitivity and commitment to issues that affect women in distinctive ways. In particular, we expected women's self-proclaimed legislative priorities to be somewhat different from men's priorities. Our hypotheses were confirmed. Women and men in our study were equally active on the range of legislative activities-a marked change from the 1970s. And women state legislators' lists of priority bills contained more legislation pertaining to women, children, and the family than men's lists. Critically, women were as successful as men in achieving passage of their priority bills. Thus, as hypothesized, electing women legislators did indeed appear to make a policy difference. In the years since the publication of our article, findings such as these became commonplace rather than headline grabbing. Indeed, the voluminous research published on questions related to political women and policy impact indicates that with few exceptions, from agenda creation through bill modification to policy outcomes, the presence of women has mattered. Legislative women have differed from men on bill introductions, cosponsorships, amendment activity in committees and floor sessions, floor speeches, roll call voting behavior, and policy outcomes. Looking back, embedded in the collective scholarship of the time was a certain kind of optimism not only about political outcomes but also about how political dynamics could or would change for the better with more women in office. The questions evolved from whether women mattered to how much and in how many ways. Many activists and scholars forecast that this would happen sooner rather than later. A recent column by Ellen Goodman (2007) notes that Associate Justice Ruth Bader Ginsburg once predicted that women would achieve full legal equality by 1978. Yet time has a way of making our expectations look rosier-or at least less straightforward-than was probably warranted. In fact, instead of the proportions of women in state and federal office rapidly increasing, women's numbers in legislatures have not risen a great deal since 1988. At that time, women constituted 15.8 percent of state legislators across the nation and 5 percent of members of Congress. Now the percentages are 23.5 percent at the state and 16. …
