Three-quarters of those responding to the IBOPE Zogby International poll said they believe Maj. Nidal Malik Hasan should be sentenced to death if he is convicted of killing 13 people and 62 percent said they strongly support the death penalty. Only 18 percent would oppose the death penalty and 6 percent were unsure.
Hasan is awaiting court martial for the 2009 shooting spree. While the death penalty is an option, the U.S. military has not put anyone to death since 1961.
The interactive poll surveyed 2,297 registered voters July 22-25. The margin of error is 2.1 percentage points.
