With the general election five months away, more Outside cash is making its way into the Alaska campaign to legalize marijuana.

The Marijuana Policy Project injected $140,000 into the Campaign to Regulate Marijuana Like Alcohol in Alaska at the end of May, according to filings with the Alaska Public Offices Commission. It marks the second largest donation the campaign has received this election season and pushes the contribution total for the campaign just over the half-million dollar mark.

In comparison, the group opposing the measure, Big Marijuana. Big Mistake. Vote No on 2, has raised a mere $31,000 since organizing in April. Most of that money came from a single donation from the Chenega Corp., an Alaska Native village corporation based in Anchorage, which gave $25,000 to the campaign last month.

At stake is Ballot Measure 2, an initiative that would regulate and tax marijuana like alcohol in Alaska. If approved, the initiative would regulate the production, sale, and use of marijuana to adults 21 years of age and older and tax its commercial sale. Alaska would become the third state to legalize marijuana, behind Washington and Colorado. The initiative's language is largely based on Colorado's law.

Proponents say the measure is long in coming and that the "prohibition" on marijuana isn't working. Opponents argue that it's too much, too soon, and that Alaska doesn't need to be the testing ground for marijuana legalization. Polls conducted earlier in the year put support for the initiative at around 50 percent.

The $140,000 doesn't mark the biggest donation from the Marijuana Policy Project, a national group that works to advocate for marijuana legalization across the U.S. In March, the organization contributed $210,000 in cash to the Alaska campaign. It also sent one staff member, Chris Rempert, to serve as campaign director.

Pro-legalization campaign spokesman Taylor Bickford said the donation will be used to "continue educating Alaskans" about the benefits of legalizing marijuana here. He said it was not intended to serve as a response to the large donation from Chenega.

"We have our own strategy and our own plan that we will be executing between now and November," he said.

Deborah Williams, spokeswoman with the Big Marijuana. Big Mistake. Vote No on 2 campaign, was not surprised to hear about the large donation Thursday, nor was she concerned, she said.

"We always anticipated we would be grossly outspent," Williams said.

The anti-legalization campaign has focused on maintaining a grassroots presence, working more to start conversations and participate in forums that "get the truth of this initiative out" Williams said.

Williams noted that other Alaska political battles have proved that Alaskans don't take well to Outside groups pushing agendas in Alaska.

"No matter how much money the Marijuana Policy Project and other Lower 48 entities put into this battle, they can't eliminate those truths," Williams said.

Bickford rejected the idea that the Marijuana Policy Project was pushing any sort of agenda. He said the group has been working to reform marijuana policy in Alaska for 20 years, and in that time has built meaningful connections in the state.

"Alaskans are going to focus on the issues. They're not going to focus on distractions and fundraising," he said.

What the campaign will look like from here remains to be seen. Bickford noted that with the U.S. Senate race dominating traditional advertising media right now, most campaigns are in the process of figuring out "how to deal with that."
