According to the web site, they are a "Network of principled mothers, grandmothers, daughters, & guardians of our nation's children dedicated to the 9 Principles & 12 Values," referring to the 9:12 Project, the brainchild of Glenn Beck. Here's the caption beneath the video you can watch above:
On Friday September 25, 2009 Glenn Beck had a special entitled “The Mother’s Challenge: A 9.12 Project.” During the final thoughts section Dr. Frank Luntz said, “If you begin everything with ‘as a mom…‘ You win.” That thought, and a brilliant comment by Nancy, during a discussion of the feeling of being alone, referring to her friends calling themselves “Sisterhood of the mommy patriots,” were the inspirations for starting this site.
One tweet went like this: "...in the matter of two hours last night AS A MOM added 2,000 more members. In a few days they were up to 14,000. Moms/grans join non-partisan "Mom: Sisterhood of the Mommy Patriots"
Well since it is non-partisan and I hate phony, mindless sheeple groups like this, plus I'm a daddy, I should join for balance. After all, it's non-partisan, whatever that means.
