Public opinion and the eighth amendment: Is there a national consensus on the death penalty for child rape?

In Kennedy v. Louisiana (2008), the United States Supreme Court banned the death penalty for child rape, citing a "national consensus" against capital punishment in such cases. Five states have recently passed laws allowing the death penalty in these cases, leading to a potential constitutional challenge. This study investigates whether there is a national consensus that the death penalty is never an appropriate punishment for child rape.

We hypothesized that support for the death penalty would be greater when participants evaluated a specific child rape case compared to when queried as a general policy consideration and support would be greater when heinous case facts, like those in Kennedy, were provided. Also, we hypothesized that support would be higher in the five states that recently enacted such legislation.

A nationally representative sample of 800 U.S. adults was recruited online. Participants completed general policy measures assessing support for the death penalty for child rape and were randomly assigned to evaluate one of two vignettes modeled on Kennedy: a version describing severe physical injuries and a version describing less severe injuries.

Across general policy measures, support for the death penalty for child rape ranged from 48% to 61%, depending on question phrasing. In the vignette task, support was significantly higher in the severe-injury condition (60.0%) than in the less severe condition (36.6%). General attitudes toward the death penalty strongly predicted judgments in the vignettes. Support was higher among residents of states that recently enacted child rape death penalty statutes, though substantial support was observed nationwide.

Public support for the death penalty for child rape is substantial but contingent on framing and case facts and does not map cleanly onto state legislative patterns. These findings complicate claims that either statutes or public opinion provide stable indicators of a national consensus for Eighth Amendment purposes.
