Every vote counts, people - and this is why!
Passing medical marijuana laws in Arizona would be able to clear up a little bit of the war on drugs in the state which borders Mexico. It would add to the economy, and keep money in the US rather than sending it across the border.
However, it didn't count, and chances are there were a lot of people who wanted it to pass but didn't make it out to vote.
However, Prop 203 failed. Bummer. Another one bites the dust...at least in 2010.
