The Science of Politics

The Resistance: Who is Protesting Trump and Are They Changing Public Views?

2017 saw protest movements return with a vengeance, as millions protested Donald Trump at marches for women, science, immigration, & more. But will that translate into public opinion shifts or electoral mobilization in 2018? Dana Fisher finds a lot of cross-over in concerns and participation across a year of big protests and signs it is translating into electoral mobilization. Nazita Lajevardi finds that protests and news coverage surrounding Trump's immigration executive order moved public views against the policy.

Congressional Primaries: How the Parties Fight Insurgents

2016 brought a lot of change in presidential primaries, but mostly continuity in House and Senate primaries. How will the candidates gain party support and win votes in this year's crowded primary season? Hans Hassell says party elites and donors continue to decide the vast majority of primaries by clearing the field and providing support. Robert Boatright says the story of primaries as ideological battles contributing to polarization is way oversold. Neither sees 2018 breaking the historical mold.

Does the Tax Law Signal Change in How Parties use Tax Credits and Deductions?

The U.S. has a long history of spending through the tax code, limiting revenue to provide benefits. But Congress just passed a major tax cut that limited some tax deductions, kept others, and expanded the child tax credit. How do the latest Republican efforts fit historical patterns? Christopher Faricy's recent article finds that Republicans usually limit credits and expand deductions, whereas Democrats do the reverse. Yet Joshua McCabe's research finds that the child tax credit is historically a Republican policy; but its targeting is limited by a debate focused on tax relief rather than income supplementation. Both say the latest law could limit the value and political salience of major tax deductions.

Rules Around the Senate Filibuster

The filibuster effectively means 60 votes are usually required to take action in the Senate. But Senate majorities can make or change rules to get around it. In 2017, Republicans went "nuclear" on Supreme Court nominations and used reconciliation rules to pass tax cuts (but chose not to limit the scope of the Byrd Rule). New books by Molly Reynolds and James Wallner explain when Senate majority parties use procedures to get around the filibuster. Reynolds finds parties follow their electoral and policy preferences but Wallner finds that minority party threatened retaliation can deter change. Matt talks to both about the future prospects for the filibuster and the ways around it.

Multi-Racial Electoral Coalitions for Minority Candidates

In many U.S. cities, Latinos and Asians are gaining population share in previously White- or Black-dominated areas. But the vast majority of cities still have white mayors, even those with majority-minority populations. So when do racial minorities gain representation and do they ally to support the same candidates? Paru Shah finds that majority-white and majority-black cities have resisted representation for new immigrant populations. Andrea Benjamin finds that Blacks and Latinos do sometimes vote for the same candidates, but their alliances depend on elite endorsements and racial cues. The results shed light on racial politics in our diversifying nation.

How Gun Politics and Gun Policy Polarize America

After every mass shooting, partisans retreat to their respective corners on gun control. The National Rifle Association, and the gun owners it represents, are critical forces in our politics, but they may be winning only with Republican voters and in Republican states. Matt Grossmann talks to Mark Joslyn about new research showing gun owners are moving further apart politically from non-gun-owners, with each developing a partisan culture. He also talks to Jay Barth about a new study showing that Obama's elections and NRA influence have accelerated gun policy adoption in the U.S. states, with Republican states deregulation guns and Democratic states regulating them.

How the House Freedom Caucus Gains Power in Congress

In its first few years, the House Freedom Caucus has helped take down a Speaker, choose another, and set the course of the health care debate in Congress. Matt Grossmann talks to Ruth Bloch Rubin about new research comparing them to other intra-party factions over a century of Congressional history, finding that they combine the strategies of their predecessors. He also talks to Andrew Clarke about a new study showing that the Freedom Caucus is more electorally dependent on Trump and gains more face time with him. The new research may explain why centrist and liberal groups have not been as effective.

Polarized Opinion on Climate Change and Messages that Move Conservatives

Despite increasing scientific consensus on human-caused climate change, the parties are growing increasingly divided. Matt Grossmann talks to Megan Mulling about new research on climate polarization, the factors that influence climate opinion, and how to manage the partisan divide. He also talks to Graham Dixon about a new experiment showing that highlighting free-market ideas alleviates conservative skepticism about climate change. The new research suggests we should skip the science debate and go right to the policy debate.

Why Republican Women Don't Run for Office and Why It Matters for the Gender Gap in Voting

Democratic women make up three times the share of their congressional caucus as Republican women. Matt Grossmann talks to Danielle Thomsen about her new research on how the donor networks in each party help produce this divide. He also talks to Heather Ondercin about her new research showing that the gap among officeholders may be producing the big gender gap among voters, with women increasingly seeing the Democrats as their party and men exiting the party for the same reason.
