This shows, more than anything, that the US senate(and congress in general) are out of touch with the US population. The fact that 0% support it really shocked me, I thought there would be at least one senator who would support legalization.
The fact is, these politicians keep it illegal for one reason, the US population wouldn't vote for them unless they took a hard anti-drug stance to "protect the children," thanks a lot Nancy Reagan.
The problem now is, more people are for legalization, it won't be long before senators will be shunned by voters for supporting authoritarian drug laws.
