The poll found that the measure, Amendment 64, has the support of 51 percent of likely voters surveyed, compared with 40 percent opposed. Men favor the measure more than women, a common gender split on the issue. But 49 percent of women polled said they support the measure, compared with 39 percent who said they are opposed.
Across every income bracket and in every age group except those 65 and older, more voters told pollsters they support the measure than oppose it, though some of the leads fall within the 4-percentage-point margin of error. Voters younger than 35 support the measure by a margin of 30 percentage points, 61 percent to 31 percent, according to the poll.
