Of course there's nothing really new here, re-legalization in Colorado and Washington only throws Obama's hypocrisy and our government's inadvertent (I presume) support for drug cartels into sharper focus
Obama's Pot Problem (Rolling Stone)
Ironically, if Obama succeeds in gutting the new state laws, he will essentially be serving the interests of foreign drug cartels. A study by the nonpartisan think tank Instituto Mexicano Para la Competitividad found that legalization in Colorado and Washington would deal a major blow to the cartels, depriving them of nearly a quarter of their annual drug revenues – unless the federal government decides to launch a "vigorous intervention." If that happens, pot profits would continue to flow to the cartels instead of to hard-hit state budgets. "Something's wrong," says Stamper, the former Seattle police chief, "when the lawbreakers and the law enforcers are on the same side."
In the end, the best defense against federal intervention may be other states standing up against prohibition. While pro-pot sentiment is strongest in the West, recent polls show that legalization is now beginning to enjoy majority support nationwide. "We're beyond the tipping point," says Stamper. Spurred by the victories in Colorado and Washington, legislators are already moving to legalize pot in Massachusetts, Rhode Island, Vermont, Maine and Iowa. "It's time for the Justice Department to recognize the sovereignty of the states," Gov. Jerry Brown of California declared. "We don't need some federal gendarme to come and tell us what to do."
Obama, the former constitutional-law professor, has relied on the expansive powers of the chief executive when it serves him politically – providing amnesty to a generation of Dream Act immigrants, or refusing to defend the Defense of Marriage Act in court. A one-time pothead who gave a shout-out to his dealer in his high school yearbook, Obama could single-handedly end the insanity of marijuana being treated like heroin under the Controlled Substances Act with nothing more than an executive order.
