Here David Kopel's analysis:
Judge Sotomayor's record suggests hostility, rather than empathy, for the tens of millions of Americans who exercise their right to keep and bear arms.
And from Damon Root at Reason Online:
Equally troubling is Sotomayor's record on the Second Amendment. This past January, the Second Circuit issued its opinion in Maloney v. Cuomo, which Sotomayor joined, ruling that the Second Amendment does not apply against state and local governments. At issue was a New York ban on various weapons, including nunchucks. After last year's District of Columbia v. Heller, which struck down DC's handgun ban, attention turned to whether state and local gun control laws might violate the Second Amendment as well.
"It is settled law," Sotomayor and the Second Circuit held, "that the Second Amendment applies only to limitations the federal government seeks to impose on this right." But contrast that with the Ninth Circuit's decision last month in Nordyke v. King, which reached a very different conclusion, one that matches the Second Amendment's text, original meaning, and history:
We therefore conclude that the right to keep and bear arms is "deeply rooted in this Nation's history and tradition." Colonial revolutionaries, the Founders, and a host of commentators and lawmakers living during the first one hundred years of the Republic all insisted on the fundamental nature of the right. It has long been regarded as the "true palladium of liberty." Colonists relied on it to assert and to win their independence, and the victorious Union sought to prevent a recalcitrant South from abridging it less than a century later. The crucial role this deeply rooted right has played in our birth and history compels us to recognize that it is indeed fundamental, that it is necessary to the Anglo-American conception of ordered liberty that we have inherited. We are therefore persuaded that the Due Process Clause of the Fourteenth Amendment incorporates the Second Amendment and applies it against the states and local governments.
This split between the two circuits means that the Supreme Court is almost certain to take up the question in the near future. What role might soon-to-be Justice Sotomayor play? As gun rights scholar and Independence Institute Research Director Dave Kopel told me via email, Sotomayor's opinions "demonstrate a profound hostility to Second Amendment rights. If we follow Senator Obama's principle that Senators should vote against judges whose views on legal issues are harmful, then it is hard to see how someone who supports Second Amendment rights could vote to confirm Sonia Sotomayor."
And so we continue on the hell-bound train. If Maximum Barry had his heart set on a female Hispanic Justice with an "empathetic" resume and "varied life experience," America would be far better served by Daisy Fuentes.
