Monday, the city of San Diego is set to debate the last remaining question before the City Council about marijuana: Where should businesses that manufacture, cultivate, distribute and test it be allowed? Or should they be allowed at all? Many people have no idea what’s going on or the profound changes in law, culture and economics that are about to hit San Diego.

The mayor’s use of his veto power to restore special election funding and take a shot at opponents was a power move that could change the politics of city budgets for years to come. And it was only the latest of many such moves provoked by novel interpretations of, and actual changes to, the City Charter.

Monday, members of the City Council found out that to change the city budget the mayor proposes each year, they ultimately need a supermajority of six votes, not just a simple majority.
