Who polled for the N.C. Family Policy Council?

The conservative advocacy group today announced the results of a recent poll on gay marriage done by Advantage Inc. 

The Arlington, Va.-based company has been described by the Washington Post as a "national political, fundraising and direct-marketing firm" that works for Republicans. 

Its Web site describes its specialties as get-out-the-vote efforts, online town halls, automated messaging and survey research.

The Family Policy Council of West Virginia released the results of a similar poll on gay marriage in October.

A company spokesman would not give further information about the poll, citing a policy against discussing any work done for clients.
