California's proposition 19 -- or Prop 19 as most refer to it -- has been in the spotlight this election day 2010, bringing particular attention to marijuana and California. It's not just Californians who are talking, either, as the whole nation seems to have an opinion on the controversial measure that would make the possession and cultivation of marijuana legal in the state. If passed, Prop 19 would also authorize cities and counties to regulate and tax commercial marijuana production and sales.
