Yes, a majority of Americans still favor the death penalty. But that majority has plummeted over the last two decades, as the Pew Research Center found last year.
In 1996, 78 percent of Americans were in favor of capital punishment while just 18 percent opposed it. In 2013, support had fallen to 55 percent while opposition had risen to 37 percent. (If you don’t feel like doing math: The gap between supporters and opponents shrunk by 42 percentage points, a pretty huge swing.)
