Guess who is lobbying against marijuana legalization?

Yup, beer distributors and the police.  Ryan Grim of The Huffington Post does a very nice job on the politics:

The California Beer & Beverage Distributors is spending money in the
state to oppose a marijuana legalization proposition on the ballot in November,
according to records filed with the California Secretary of State. The beer sellers are the first
competitors of marijuana to officially enter the debate; backers of the
initiative are closely watching liquor and wine dealers and the pharmaceutical
industry to see if they enter the debate in the remaining weeks…

Public Safety First is largely funded by a different industry whose interests are threatened by the legalization of marijuana: law enforcement. Police forces are entitled to keep property seized as part of drug raids and the revenue stream that comes from waging the drug war has become a significant source of support for local law enforcement. Federal and state funding of the drug war is also a significant supplement to local forces' budgets.

Amusingly, the Teamsters and the teachers (!) are supporting legalization:

The Service Employees International Union, a major presence in California, has endorsed the proposition. The Teamsters in September made its first successful foray into organizing pot growers. The United Food and Commercial Workers is backing the initiative and organizing cannabis club employees in the Bay Area. The teachers union, citing the revenue that could be raised for the state, is also backing the initiative.
