Victor Davis Hanson‘s latest column for National Review Online offers a provocative comparison between today’s sanctuary cities and the 19th-century Confederate states.

There are now 340 sanctuary cities in the United States — and the list is growing. All of them choose to ignore federal immigration law by refusing to report detained undocumented immigrants to federal authorities under most circumstances.

Partly as a result, deportations of those who entered the U.S. illegally are at a 10-year low — even according to the Obama administration’s new rigged redefinition of deportation as also occasionally preventing illegal entry at the border. …

… In the 19th century, the Supreme Court issued a number of rulings prohibiting particular states from ignoring federal laws — from unpopular tax policies to the establishment of Native American reservations.

The most prominent nullificationist was Senator John C. Calhoun, a South Carolina states-rights advocate and the spiritual godfather of sanctuary cities. Calhoun declared, for example, that federal tariffs should not apply to his state.

Apparently, sanctuary cities do not understand the illiberal pedigree of federal nullification, which was at the heart of the Confederate secessionist movement of 1861. In the 1960s, segregationists declared that Supreme Court decisions and integration laws did not apply to their states. In some states, local law enforcement refused to cooperate with federal authorities to integrate schools.

What would San Franciscans do if conservative counties and towns followed their lead? Perhaps a rural Wyoming sheriff can now look the other way when he spots a cattleman shooting a federally protected grizzly bear or predatory timber wolf — or at least shield the cattleman from federal officials. Should public schools in Provo, Utah, start the day with school-wide prayers?
