This week in the magazine, Ryan Lizza writes about Governor John Hickenlooper, of Colorado: “Hickenlooper began his tenure as a sensible centrist. But, instead of emphasizing the issues on which he campaigned… he has found himself addressing a range of liberal social issues: gun control, civil unions, and a new law legalizing marijuana.” In March, Hickenlooper signed three gun-control laws that were among the strictest in the county, and he has called on the House to legalize same-sex unions. However, his opposition to marijuana legalization remains, despite the passage, last fall, of a law in Colorado that legalizes the drug. Lizza writes that Hickenlooper recently “gathered his senior staff around a conference table in his office to discuss the design of an anti-marijuana public-awareness campaign.” As we wait to see what they come up with, here’s a look at past anti-drug television campaigns.
