As predicted, the big money has started to pour into the battle over Proposition 23, the California ballot measure that would suspend the state’s global warming law.

Over the past two weeks, the No on 23 forces have collected more than $1.8 million in contributions while the Yes campaign has taken in only $6,500, according to California Secretary of State records. (See the graphic below for more detail on who’s giving what to whom.)
