In Arizona, a late-August Arizona Republic/Morrison/Cronkite News poll of 784 registered voters found that 50 percent supported marijuana legalization, 40 percent opposed it, and 10 percent remain undecided. That result is sharply at odds with a July poll of likely voters showing that only 39 percent said they favored the measure.

In California, a post-debate SurveyUSA poll of 751 likely voters found that Proposition 64, which would legalize, tax and regulate the sale of recreational marijuana, is supported by 52 percent of the electorate and opposed by 41 percent, with 6 percent undecided. This is a lower margin than some other recent polls there, which have pegged support at 60 percent or more.

Across the country in Massachusetts, the marijuana legalization measure there enjoys 53 percent support among likely voters, according to a recent WBZ-UMASS Amherst poll of 700 likely voters. Forty percent oppose it, while another 7 percent are unsure. That’s also a turnaround from an earlier poll of 900 registered voters, which found only 41 percent supported the measure.
