Washington State's legalization initiative still has a sizable lead:
First, a survey conducted by SurveyUSA and KING 5 NEWS showed 55 percent of voters were planning to vote YES on I-502, which would decriminalize and regulate marijuana use in the state. Only, thirty-six percent said they oppose it and 8 percent remained undecided.
Other data just released by KCTS9 Washington, has I-502 ahead among both registered and likely voters. 50.9% of registered voters support the measure, with 40.8% against it. Likely voters back I-502 by 47.1% with 40.1% opposed.
