From Cato:
"The Supreme Court is very likely to review this case, which means we’re about a year away from a definitive ruling from the high court on the meaning of the Second Amendment" (http://www.cato-at-liberty.org/2007/03/09/landmark-second-amendment-ruling-today/)
This makes a very good 2008 election issue for the GOP, bringing the gun issue into discussion which favors the GOP. Also brings into the discussion the importance of SCOTUS judges.
All the more reason NOT to nominate gun-grabbers like Giuliani or Romney.
