The Public Policy Institute of California is out with their post election survey, and among the many issues they focus on is why Californians voted for or against Proposition 19, the initiative that would have legalized marijuana. This measure failed last month by a seven points, with 46.5% voting yes and 53.5% voting yes.

According to the poll, Republicans where a main cause of Prop 19 failure. Only 27% of the Republicans who voted this year cast their ballot for Prop 19, while 73% voted against the measure. Democrats and independents supported the measure at near identical rates, 56% of Democrats and 55% of independents voted yes. This shows that at least some of Prop 19′s problems came down to bad timing. This 2010 midterm election had unusually high turnout among Republicans.

A new poll of likely California voters shows 49 percent support a November ballot measure to legalize, regulate and tax marijuana, while 48 percent oppose it. Opposition is high among women and Latinos, with younger voters more strongly in favor.
