A Year in, Gavin Newsom Is Still Fighting Trump. Is He Doing Enough to Govern California?
USA Today
2019-12-15
Some critics contend that California Gov. Gavin Newsom’s first year in office has been diluted by his feud with President Trump, resulting in lack of progress on big state issues. “He ran as a leader of the Trump resistance, and he’s been all-in there and gets full marks,” said Thad Kousser of UC San Diego. “So, the next step will be to really get a coherent policy agenda set and implemented.”

Democratic Senators lost in battleground states after voting against Kavanaugh
USA Today
2018-11-07
Indiana Sen. Joe Donnelly lost to Republican Mike Braun. North Dakota Sen. Heidi Heitkamp lost to Republican Kevin Cramer. Florida Sen. Bill Nelson's race was called for Republican Rick Scott, but the final result will likely wait on a mandatory recount. Missouri Sen. Claire McCaskill lost to Republican Josh Hawley. "These senators paid the ultimate political price for their vote," said Thad Kousser, a political science professor at the University of California San Diego.
Will changing how we vote change who votes?
University of California
2018-11-01
UC San Diego political scientist Thad Kousser is leading a team of researchers from five UC campuses to find out. “What will the act do to turnout? And more importantly, how will it affect who turns out?” Kousser said. “There are a lot of gaps in California representation along racial and ethnic lines, and along economic and educational lines. Will the new system shrink these gaps or widen them?”...

Turning Out Unlikely Voters? A Field Experiment in the Top-Two Primary
Political Behavior
Seth J Hill, Thad Kousser
2016 Those who turn out in American primary elections are a small and unrepresentative subset of the population. Why do citizens forgo participation in nominating contests yet vote in general elections? We argue that limited contact lowers participation in primary elections. We present results from a randomized field experiment with near 150,000 letters in California’s 2014 primary. Each letter went to one of the four million Californians who had participated in recent general elections but not in primaries. We find that a single letter increased turnout by 0.5 points from a base rate of 9.3 percent. This increase is more than twice the average effect calculated in a recent meta-analysis and represents a proportional increase of 5.4 percent. Our experiment shows that registrants who typically abstain from primaries—and who are thus often ignored by campaigns—can be effectively mobilized.
Reform and representation: a new method applied to recent electoral changes
Political Science Research and Methods
Thad Kousser, Justin Phillips, Boris Shor
2016 Can electoral reforms such as an independent redistricting commission and the top-two primary create conditions that lead to better legislative representation? We explore this question by presenting a new method for measuring a key indicator of representation—the congruence between a legislator’s ideological position and the average position of her district’s voters. Our novel approach combines two methods: the joint classification of voters and political candidates on the same ideological scale, along with multilevel regression and post-stratification to estimate the position of the average voter across many districts in multiple elections. After validating our approach, we use it to study the recent impact of reforms in California, showing that they did not bring their hoped-for effects.
Kingmakers or cheerleaders? Party power and the causal effects of endorsements
Political Research Quarterly
Thad Kousser, Scott Lucas, Seth Masket, Eric McGhee
2015 When parties make endorsements in primary elections, does the favored candidate receive a real boost in his or her vote share, or do parties simply pick the favorites who are already destined to win? To answer this question, we draw on two research designs aimed at isolating the causal effect of Democratic Party endorsements in California’s 2012 primary election. First, we conduct a survey experiment in which we randomly assign a party endorsement, holding all other aspects of a candidate’s background and policy positions constant...
No strength in numbers: The failure of Big-city bills in American state legislatures, 1880–2000
American Political Science Review
Gerald Gamm, Thad Kousser
2013 Do big cities exert more power than less populous ones in American state legislatures? In many political systems, greater representation leads to more policy gains, yet for most of the nation's history, urban advocates have argued that big cities face systematic discrimination in statehouses. Drawing on a new historical dataset spanning 120 years and 13 states, we find clear evidence that there is no strength in numbers for big-city delegations in state legislatures. District bills affecting large metropolises fail at much higher rates than bills affecting small cities, counties, and villages...
Party power or preferences? Quasi-experimental evidence from American state legislatures
The Journal of Politics
Gary W Cox, Thad Kousser, Mathew D McCubbins
2010 Can majority parties control legislative outcomes by controlling the agenda, or are roll-call patterns simply the product of legislators’ preferences? We argue that, holding members’ preferences constant, the majority party’s ability to set the agenda gives it the power to influence legislative outcomes. We present the implications of this view of party power formally and then explore them empirically in two quasi-experiments from American state legislatures...
