Fifty-six percent of the delegates at the Denver County Republican Assembly voted in support of a resolution to regulate marijuana like alcohol in the Centennial State. While the initiative, known as Amendment 64, did not receive the two-thirds majority required to adopt it as a plank in the party's platform, advocates are hailing the vote as significant.

"It is impressive and encouraging that a majority of some of the most active Republicans in Denver voted to endorse the initiative," wrote the Campaign to Regulate Marijuana Like Alcohol in a statement. "As more and more Colorado citizens see their friends and neighbors voicing their opposition to marijuana prohibition, we expect support for the initiative will continue to grow."

The Assembly, which voted Saturday on the initiative, did adopt a resolution affirming that medical marijuana is a 10th Amendment issue that should be left to the states.

Under a medical marijuana law enacted in 2000, Colorado patients with a note from their physician can access marijuana from a dispensary. But federal prosecutors have ramped up enforcement around medical marijuana in recent months, resulting in the closure of dozens of dispensaries around the state.

The vote comes shortly after television evangelist Pat Robertson took to the airwaves on "The 700 Club" to condemn arrests for marijuana possession.

"On the heels of the Pat Robertson endorsement of Amendment 64, it is great to see increasing support for regulating marijuana like alcohol across the ideological spectrum," the Campaign to Regulate Marijuana Like Alcohol added.
