Civil Beat surveyed 780 registered voters April 7-9 using interactive voice response technology (touch-tone polling) on their views on marijuana, GMO labeling, the Honolulu rail project and top elected officials.

The poll included landlines and cell phones, and had a margin of error of 3.5 percent. The margin of error for Oahu-only respondents was 4.2 percent.

In all the surveys, calls were made to land lines and cell phones. Cell phones were contacted in compliance with federal law.
