From the WSJ:
Firearms manufacturers are well aware that if semiautomatic rifles are banned, bolt-action guns are next. It is a mistake to cede a millimeter on any issue, because it simply invites more demands. People in the gun culture know their opposition… Consider, by way of contrast, the foolish actions of Chesapeake Energy, a major producer of natural gas. Time magazine revealed last year that Chesapeake gave the Sierra Club $26 million. Presumably the Machiavellian reasoning was that the Sierra Club would use this money to attack Chesapeake’s competitor, the coal industry… Now the Sierra Club is trying to shut down hydraulic fracturing—the entire basis of Chesapeake’s natural-gas business. According to reports this week, the natural-gas boon from fracking could be a boon to the U.S. economy for 30 years, if the industry doesn’t fumble the opportunity… If Chesapeake’s managers had understood the environmental movement, they never would have subsidized Sierra Club.
