Lawyers, help me out here.

Edward McKenna is the mayor of Red Bank, New Jersey.

In a normal week, he receives about 10 faxes from constituents. In three days last November, McKenna says he got more than 200.

EDWARD McKENNA: "Those faxes all purported to come from people who said they were Red Bank residents. In fact, each fax started out by saying, "I am a Red Bank resident and I vote."

These so-called residents all wrote in support of new legislation to increase competition in the cable industry. McKenna noticed the faxes had names, but no signatures.

EDWARD McKENNA: "When I called them, a number of them said they had not authored any such letter. Nor did they authorize anyone to send it on their behalf."

He says the traced the fax number back to an organization funded by the telephone giant Verizon.

Dawn Holian with Common Cause has studied these front groups, also known as "astroturf."

Is it legal to send correspondence to public officials on behalf of residents without their permission?  I mean I know it's unethical, but is it legal?
