You know such votes happened and passed in other states as well.
For the legalization of medical marijuana, not recreational marijuana, yes. I believe 9 out of the 11 states used a public referendum rather than the state legislature to legalize.
You've got Soros and NORML and the MPP and the DPA and all these outside pro-marijuana organizations funding and organizing these state measures, coupled with a motivated minority, and you end up with 51% of those who voted establishing state policy. That's not representative of the state.
You say you disagree with the method, yet you support the results as representing the will of the state. What gives?
