WATCH: NOM Wants SCOTUS to Ignore National Support for Marriage Equality

Last week saw a flurry of amicus briefs submitted to the U.S. Supreme Court in the pending marriage equality cases, originating from various law firms, politicians, civil rights groups, faith groups, businesses, and more. But the National Organization for Marriage's brief might be the strangest.

Judging by the arguments in NOM's brief, one might think the organization is unfamiliar with the way the arguments are structured for the April 28 Supreme Court hearing. While the consolidated cases originated from four states, the high court will only be considering two questions — whether the Constitution requires states to issue marriage licenses to same-sex couples, and whether it requires states to recognize licenses issued to those couples by other states. NOM's brief barely acknowledges either query.

Instead, NOM presents an argument that is irrelevant and untrue. "Recent national surveys show that the American people remain closely divided over same sex marriage," the organization writes.

But that's just flat-out false: The most recent surveys from The Wall Street Journal, CNN, Rand, and The New York Times show the percentage supporting marriage equality in the upper 50s or lower 60s nationwide. Opposition is generally in the 30 percent range and hasn't polled above 50 percent in a major national survey at any time in the last five years.
