It's not on their website yet (I'll try to post the link when it comes up), but they just repeated the 90% meme in an article about the Mexican drug war.
So much about the whole notion is flawed. "Mexican Drug War?" It's every bit as productive and successful as the "War on Air." 1) There isn't one 2) It would fail miserably, because 3) the idea of taking drugs out of Mexico is like trying to empty the Pacific Ocean into space with a bucket brigade, so the fish won't drown. Aside from intense laughter, the fish aren't likely to be helping.
But drawing this 'legal' situation into the spotlight isn't just about trying to further gun control. Keep sabotaging the economy, and soon, we'll be so cozy with Mexico 'helping' them, that gosh, why not just erase the borders? The United States of Amexica!
Drugs? War? Mexico? There's no way to combine any of those words without laughing really hard.
