As noted in the introduction to this article, the American public has maintained its position of support for capital punishment for murder. However, when given a choice between the death penalty and life imprisonment without parole, support has traditionally been significantly lower than polling which has only mentioned the death penalty as a punishment. In 2010, for instance, one poll showed 49 percent favoring the death penalty and 46 percent favoring life imprisonment while in another 61% said they preferred another punishment to the death penalty. The highest level of support for the death penalty recorded overall was 80 percent in 1994 (16 percent opposed), and the lowest recorded was 42 percent in 1966 (47 percent opposed). On the question of the death penalty vs. life without parole, the strongest preference for the death penalty was 61 percent in 1997 (29 percent favoring life), and the lowest preference for the death penalty was 47 percent in 2006 (48 percent favoring life).
