The 5 Stages to Legalization

I found this and thought it was pretty accurate.  It is from a new york times article you can find here.

Stage 1. Bill Clinton: I smoked but I did not inhale.

Stage 2. Al Gore: I smoked, it was wrong, I regret it, shame on me.

Stage 3. Michael Bloomberg (asked if he’d tried pot): “You bet I did and I enjoyed it.”

Stage 4. Barack Obama: “I inhaled frequently — that was the point!”

Stage 5. Public Figure to Come: Yes, I smoke the occasional joint.

How long until stage 5?
