This Mark Murray piece seems to make a lot of sense:
Yesterday’s Supreme Court decision on the 2nd Amendment elevated an issue — guns — that hadn’t received that much attention until now. Remembering that the subject hurt Al Gore in 2000 and somewhat damaged Kerry’s image in 2004 (after his widely panned hunting excursion) will guns also be a problem for Obama? On the one hand, many of the swing states (actually check that, EVERY swing state) are places where the electorate tends to have pro-gun views and where the Mike Bloomberg position wouldn’t fly. On the other hand, as some have pointed out today, the Supreme Court ruling may actually help Obama because Republicans might no longer be able to argue that Democrats want to take your guns away. “The Supreme Court has said you can’t do that,” Democratic pollster Geoff Garin told the Washington Post.
Given that ownership of guns as an issue has been taken off the table by the Supreme Court, and that Scalia, one of the most conservative members of the Court wrote the majority report and affirmed almost every bit of gun control legislation short of outright bans in his opinion, it sure would seem that it is going to take some real creativity on the part of Republicans to get any traction on the issue of guns anymore. The only thing they could probably do is to lurch rightward, but then they run the risk of alienating the middle, who I presume favor many common sense approaches to gun control (not allowing them in bars, not allowing felons to own guns, etc.).
At any rate, this could be a major loss for Republicans in states like West Virginia, where the gun issue went a long way to defeating Al Gore. SCOTUSBLOG has a related discussion of the future of gun control here.\
