Angus Reid finds that a majority of Americans (53%) support the legalization of marijuana. 68% think the "War On (Some) Drugs" has been a failure.
Those numbers aren't even particularly split down party lines. 61& of Dems, 55% on Indies and (surprisingly) 43% of Pubs support legalization.
With the entire Left Coast looking at legislation and/or ballot measures to decriminalize the devil weed (and, hopefully, start making some tax revenue off the sale of it) it seems like it's just a matter of time before more states follow suit.
Next step will be to empty the prisons of all those locked up on pot charges.
