Two months out from election day, positions appear to be hardening in the battle over legalizing marijuana in Colorado. A new Public Policy Polling survey [10] shows Amendment 64 [11], which would legalize and regulate marijuana like alcohol, maintaining the same nine-point lead it held last month.

PPP noted that the ballot language could be somewhat confusing, so it also asked a general question about marijuana legalization. That polled slightly higher, with 49% saying they approved and 43% saying they didn't.
That 43% who oppose marijuana legalization in general will likely represent the minimum "no" vote in November. Now, the initiative campaign must maintain the support it currently has while picking up some of those 15% of the voters who are undecided.
