That said, one of the traditional ways of getting the Supreme Court to take a case is to demonstrate that there is a "split in the circuits," i.e., one or more circuit courts has taken position X and one or more circuit courts has taken position Y, and X and Y are directly opposite positions. The Supreme Court is supposed to issue the definitive ruling in such situations.
We have a split in the circuits now on interpretation of the Second Amendment -- Fifth Circuit versus Ninth Circus. It is not strictly a numbers game, but if the DC Circuit could weigh in with the Fifth on the side of an individual right, that could be a big plus. The DC Circuit is well regarded and is often used as a parking lot for future Supreme Court justices. Their view on a subject such as this would be taken seriously.
As I keep maintaining, the system is irrevocably broken.
