A new Rasmussen poll found that 57% of American adults support the death penalty, down from 63% in the organization’s polls dating from 2009. The poll found 26% of respondents opposed the death penalty, with 17% undecided. Respondents were also asked whether they favored the death penalty for James Holmes if he is convicted of the mass shooting at a movie theater in Aurora, Colorado. Just 55% said they believed Holmes should be sentenced to death, compared to 66% who held that view immediately after the shooting in 2012. Twenty percent were undecided. Rasmussen found that Americans were less supportive of executing a defendant who is mentally ill, an issue in Holmes’s case. Respondents also had concerns about wrongful convictions, and were split on whether the death penalty deterred crime.
