Can a local newspaper allow posters on a forum to slander & name you publicly?

My ex-husband is the treasurer for a group that opposes a property tax increase. He answers questions on Internet forums to clarify exactly why he is against the increase.

There is a local newspaper that works closely with the City Council. The opposition has linked me to my ex & begun posting my name and slandering me (the publisher called them ad hominem attacks). One guy took it to other forums and claimed that he knew who I "hang out with." I'm scared.

Today, I discoverd that the editor for this paper wrote an editoral calling anyone who opposed the tax increase a "nutcase" and claimed that they had "poisoned Kool-Aid" that would kill the community. I fear further attacks and threats now. They are slow to remove the slanderous remarks.

Do I have recourse?
