It is Likely That Pot is the Biggest Crop in California

The Economist has an article positing that marijuana has surpassed wine as California's biggest crop. From the article:

"Since April the state's annual “Campaign against Marijuana Planting” has pulled 2.9m plants worth some $10 billion from back gardens, timber forests and state lands. Marijuana is now by far California's most valuable agricultural crop. Assuming, very optimistically, that the cops are finding every other plant, it is worth even more than the state's famous wine industry."

I am wondering what will happen in California after 2008 if a president who is less intent on enforcing federal drug laws is elected.
