Well, actually, the Lateef campaign made the post.
Lateef's campaign describes "Virginia New Majority" as "a non-partisan non-profit 501(c)(4) organization that has worked around the state to advance the issues you and I care so deeply about."
Non-partisan? Sure. That must be why it endorsed only Democrats.
Actually, "Virginia New Majority" is a union front group whose "board chairman, Juan Marcos Vilar, is the political director of the Service Employees International Union. Records show VNM has received political donations from the SEIU."
Now, you won't read this on VNM's website. The "More Info" link helpfully adds you to its mailing list. And other links merely direct you to its blog, which touts the desire to "bring together immigrants, African-Americans, women, youth, and working-class Virginians to build a progressive [read: "reactionary liberal"] movement in Virginia through grassroots voter organizing."
I found the more interesting and revealing information on Fairfax Underground.
Another far-Left front group. Color me surprised.
