Sources and Consequences of Polarization on the U.S. Supreme Court - PowerPoint PPT Presentation

Sources and Consequences of Polarization on the U.S. Supreme Court Brandon Bartels George Washington University

Sources of Polarization • Changing criteria for judicial appointments • Demise of patronage and political/electoral considerations • Recent phenomenon: near-exclusive emphasis on ideological reliability – No more liberal Republicans (Souter, Stevens, Blackmun) and conservative Democrats – No more “swing justices” (Kennedy and O’Connor) • Partisan polarization among political elites more generally • Strategic retirements • Result: Disappearing center….contrast from past.

The Shrinking Center Over Time • “The center was in control.” – Woodward and Armstrong (1979, 528) • Today’s Supreme Court – Low “swing” or crossover potential among nearly every justice – Justice Kennedy…. • “Swing capacity”: In close votes, a justice is likely to be in the majority for both liberal and conservative case outcomes.

Policy Outputs Over Time • On the whole, long period of low to moderate polarization, but it’s increasing…and will likely continue to increase. • Direction of policy outputs largely independent of presidential appointments (based on expectations from “ideological reliability” model)

Policy Outputs Over Time • On the whole, long period of low to moderate polarization, but it’s increasing…and will likely continue to increase. • Direction of policy outputs independent of presidential appointments (based on expectations from ideological reliability appointment model) • Vinson Court moderation – Division among FDR appointees: Douglas, Black, Rutledge v. Frankfurter, Jackson – Truman’s moderate to conservative appointees (Vinson, Burton (R), Minton, Clark)

Policy Outputs Over Time • Warren Court liberalism – Brought to you by Eisenhower (Warren and Brennan), but also FDR appointees (Black, Douglas); not Truman – Kennedy: Mixed (Goldberg v. White) – Johnson emphasized ideological reliability: Fortas, Marshall • Burger Court “center right” – Strong center, appointed by in large by Republican presidents (Stewart, Powell, Blackmun, Stevens); also White (Kennedy appointee) – Leftward drift: Stevens and Blackmun

Policy Outputs Over Time • Rehnquist Court: center- right…why not more conservative? – Stevens and Souter, liberal drift – O’Connor and Kennedy, swing justices • Roberts Court: center-right – Kennedy, the only remaining swing vote

Consequences of Polarization • Today: One person in middle who’s pivotal on most issues • Kennedy: the last “swing justice?” • “Ideological reliability” model of presidential appointment makes presidential elections even more consequential for Supreme Court policy outputs. – SC outputs will more closely track presidential ideology (Dahl). • Will someone evolve into a swing justice for institutional maintenance concerns? – E.g., Justice O’Connor • Benefits of polarization? – Legal clarity

Consequences of Polarization • Polarization paradox? – Increase in 5-4 decisions, but an increase in unanimous cases as well.

Consequences of Polarization • Polarization paradox? – Increase in 5-4 decisions, but an increase in unanimous cases as well. • Volitional v. exigent agenda (Pacelle) • Strategic voting to the extreme at cert stage; risk aversion • Increase unanimity for legitimacy purposes; offset to closely divided cases? • Back to legal clarity…bifurcated.
