I'm not american, so I haven't got a clue of where to go to find some unbiased information about the outcome
Any major US newspaper's website will information on Prop 19. I believe the vote is in early November. Try cnn.com.
Marijuana Law Reform - NORML They update daily with the latest MJ news around the world. So you can be sure as soon as something major breaks it will be right on the front page.
I'm guessing if Prop 19 passes and it being the first law of its kind in the United States, it will make world news. Everyone will hear about it. Just a guess......
With as much National interest and controversy Prop 19 is it will have a counter on MSN,CNN and FOX,just like they follow the election results.
I'm sure we'll have many people posting updates throughout the evening as the counts begin to come in.
