Two years ago, the Supreme Court heard the hotly controversial Heller case, in which it ultimately recognized a personal right to keep and bear arms under the Second Amendment. That case, which pertained only to federal (and District of Columbia) gun regulations, not state or other local gun regulations, sharply divided activists along partisan lines.
The Court is now considering McDonald v. City of Chicago, a follow-up case asking whether persons have an equivalent right against state and local governments. The familiar partisan divide has returned, but this time the more heated divide separates dueling factions on the right. Even more surprising is the subject of the debate: A 137-year-old line of Supreme Court precedent involving the Fourteenth Amendment.
