Even as the former vice-president took to the pages of The Wall Street Journal to blame Barack Obama for the deteriorating situation in Iraq, George W. Bush's drug czar, John P. Walters, is arguing in Politico that no, really, victory in the war on drugs is just around the corner. We've just got to hold the line, don't you see, especially against Barack Obama, "whose administration has facilitated marijuana legalization" despite also setting a record for federal raids against medical pot dispensaries in California.]

More important, insists Walters, is that you understand "Why Libertarians Are Wrong About Drugs." Well, OK. I know I've been wrong about drugs at times. For instance, I seriously worried that Colorado might have taxed its fully legal pot out of reach of most buyers, thus allowing a black market to thrive. But it turns out that the biggest problem in the Centennial State is how to spend extra tax revenues generated by pot sales, which are coming in 40 percent higher than expected. Oh yeah, and crime is down in Denver.
