The Science of Politics

Interest groups on both sides were ready for battle when President Trump nominated Amy Coney Barret to the Supreme Court. As Republicans vote to confirm her, how will voters respond? Jonathan Kastellec finds that interest groups have polarized the debate: starting earlier in nomination battles, with groups now fighting over nominee ideology rather than qualifications. Alex Badas finds that Supreme Court nominations have become a voting issue, but that Republican voters still prioritize them more.

As Election Day approaches, Trump intimidation efforts are increasing and Americans in both parties are worried that the other side could use unfair tactics to sway the election. Why does the public fail to serve as a check on anti-democratic practices? Matt Graham finds that only a small fraction of voters prioritize democratic principles over partisan and ideological interests. And by increasing ideological differences, polarization has hurt democracy’s valuation. Larry Bartels finds that large numbers of Republicans countenance anti-democratic moves. And it’s not based on their support for Trump, but their broader ethnic antagonism. They both say we should worry about American democratic backsliding among elites because public support for democracy won't save us. Photo Credit: Donald Trump / Public domain

Racial Protest, Violence, and Backlash by Niskanen Center

National politics gets all the attention, but many important decisions--from police reform to housing development to tackling inequality--are made by local governments. Which voices are heard in local decision-making? Jesse Rhodes finds that local elected officials are ideologically much closer to White residents in their communities than Black or Latino residents and more conservative than the people they represent. Sarah Anzia finds that organized groups like police unions and local chambers of commerce influence local policy across the board. They both say that local policy choices follow the loudest voices of the repeat participators.

The Republican Party runs populist culturally conservative campaigns, but its policymaking mainly benefits the already well-off. In a time of rising economic inequality, how do they get away with that? Jacob Hacker and Paul Pierson find that Republicans have to ramp up the outrage stoking due to their lack of broad policy appeals. The Republican Party’s economic positioning is internationally extreme and threatens to undermine US democracy. In this conversational edition, we assess plutocratic populism and its consequences.

Today, Black Americans are the strongest Democratic constituency and White Southerners are the strongest Republican group—but it used to be the other way around. The usual story places 1960s civil rights policymaking at the center of the switch, but an important prior history in the North and the South made it possible. Keneshia Grant finds that the Great Migration north changed the Democratic Party because Black voters became pivotal in Democratic cities like New York, Chicago, and Detroit, leading politicians to respond, including new Black elected officials. Boris Heersink finds that Southern Republican state parties became battles between racially mixed and lily-white factions, mostly for control of patronage due to national convention influence. The lily-white takeovers enabled early Republican gains in the South.These trends predated national civil rights policymaking and help explain how we reached today’s divided regional and racial politics.

Billions of dollars in donations will flow to candidates this year. Citizens suspect all that money buys the donors' influence. But just how different are donors’ views in each party from those of citizens? Neil Malhotra finds that Republican donors are more conservative than Republican citizens on economic issues but Democratic donors are more liberal on social issues. Both parties’ donors are more pro-globalization than their voters. So which do the candidates follow: the donors or the voters? Jordan Kujala finds that donors make candidates more inconsistent with their electorates and increase polarization in both parties.

The Supreme Court finished its term with a flood of momentous decisions, tacking to the center with Chief Justice John Roberts crafting most of the majorities and the Court agreeing with public opinion nearly all of the time. Is the Court worried about its public non-partisan stature? And does it need to be? Alison Higgins Merrill finds that support for the Supreme Court is high but declining, partially in response to ideological trends. Michael Nelson finds that public support for the Supreme Court is relatively stable and most people’s negative reactions to decisions don’t last. They both discuss what we can learn from Roberts and the Court this term.

Protests over police brutality have gripped the nation. But how do racial minorities in highly policed communities think about political action and mobilize to fight unfairness, when they are facing force and indignities that often lead to withdrawal? Vesla Weaver finds complicated but negative attitudes toward police. Overpolicied communities are often motivated for change, though not always traditional politics. Hannah Walker finds that criminal justice experience can mobilize people if they perceive external unfairness, including in the immigration enforcement system and overpolicing.

Republicans lost control of the House in 2018 and now could lose the Senate this year. Their fortunes seem tied to Trump and his agenda, but new research suggests they would be better off trying to distinguish themselves from him and his policies. Sarah Treul finds that votes to repeal Obamacare cost Republicans seats in Congress in 2018. They did not listen to their constituents at Town Hall meetings and the repeal effort resulted in lower vote share. Andrew Ballard finds that Trump endorsed a lot of Members of Congress in 2018 but it actually hurt those endorsees, stimulating the opposition more than the supporters.
