This fall, California voters will decide whether to legalize recreational marijuana. Law enforcement groups have donated most of the money to defeat the measure, Proposition 64. Another group thatís contributed to the anti campaign is less expected: The California Teamsters.
Campaign records show that the California Teamsters Public Affairs Council, which represents 250,000 members, donated $25,000 in March to the Coalition for Responsible Drug Policies, a group lobbying against Prop. 64. It was a relatively large amount for the opposition side, which has been vastly outspent by proponents of legalization.

However, the California Teamsters have since had a change of heart, according to their chief lobbyist, Barry Broad.
