Maybe he should listen to young people about this instead of lecturing them on their priorities. We can end the prohibition laws now while we still argue about climate change, jobs, and war. Other unrelated issues aren't stopping us from ending this failed era of prohibition.
Whenever a politician says "What I say to young people is...." he's not really talking to young people at all, just reassuring older people who vote. Saying that young people should de-emphasize legalization is like saying they should study instead of party. Nobody listens except people to whom it doesn't apply.
When Obama seized the opportunity provided by CO & WA he advanced the cause of legalization by at least a decade, I figure, maybe more. He could have stuffed retail with the wave of his hand. He kept the dogs off us at the risk of them turning against him.
I thought it rather artfully done, too, because he made it so that it's not about him. Hell, too many people leap on any opportunity to be against anything just because he's for it.
Money? Sin taxes? Paying tribute? Buying off the Man? Beats getting busted, every time.
