Gun-control advocates are quietly acknowledging that Fenty (D) is in a difficult spot. Across the country, many of them and their attorneys have been meeting in conference rooms to analyze the potential damage that could be done nationwide if the D.C. law falls apart. Some fear that an adverse Supreme Court ruling could lead to more gun lobby challenges and the collapse of tough gun regulations in New York, Chicago and Detroit. Other potential casualties include federal laws that require background checks for gun buyers or ban the manufacture of machine guns for civilian use.
