Proposition 19, the initiative to legalize, regulate, and tax marijuana in California, is maintaining a narrow lead, according to poll results released Wednesday by SurveyUSA. The poll of 621 likely and actual voters (early voting started two weeks ago) was taken between Friday and Sunday and had the initiative leading 48% to 44%, with 8% undecided.

[Editor's Note: A Public Policy Institute of California poll released Wednesday night had contrary results. It was too late for this week's Chronicle, but you can read about it here.]

 

The findings are roughly in line with more than a dozen other polls taken on Prop 19 this year, all but four of which have the measure leading. According to the Talking Points Memo Polltracker, the average of all polls has Prop 19 leading 46.8% to 44.5%. The polltracker, however, has not been updated with this latest SurveyUSA poll. Once it is, support will increase slightly, while opposition will decrease slightly.

SurveyUSA has done six polls on Prop 19, and they show support declining slightly from 50% in the earliest surveys. They also show opposition rising slightly. It was at 40% in July, peaked at 43% in September, then declined to 41% early this month before rising to 44% in the current poll.

With a four percent margin of error, this latest SurveyUSA poll shows a very tight race indeed. With undecideds beginning a not unexpected peeling off toward a "no" vote, voter turnout is going to be key to victory on November 2.
