Marijuana legalization is likely coming to Washington State. Initiative 502, which would legalize marijuana under state law, still leads in PPP’s last poll of the state. According to PPP,  53 percent of of likely voters in Washington plan to support I-502 while 44 percent plan to vote against it. From PPP:

Washington State – Initiative 502
PPP (11/1-3)
Initiative Measure No. 502 would license and regulate marijuana production, distribution, and possession for persons over 21; remove state law criminal and civil penalties for activities that it authorizes; tax marijuana sales; and earmark marijuana-related revenues. If the election was today, would you vote ‘yes’ or ‘no’ on Initiative 502?
Yes 53%
No 44%
Undecided 3%

All the recent public polling in Washington has found I-502 above the 50 percent mark needed for passage. The SurveyUSA poll from last week found it leading 56 percent to 37 percent and the Washington Poll had it ahead 55.4 percent to 37.6 percent.

During the 2010 election, PPP’s final poll of Proposition 19 in California ended up very accurately predicting how much support that marijuana legalization initiative would get. PPP’s last poll right before the 2010 election found Prop 19 at 44 percent support and on election day it got 46.5 percent of the vote. Assuming PPP’s polling of marijuana initiatives ends up being as accurate this election as it was last cycle, Washington should make history by approving I-502 tomorrow.
