The woman who called Obama an Arab was interviewed after the town hall meeting.

She still believes Obama is an Arab and thinks McCain was just afraid to deny that. She said she got the information from the local Republican party and copied a letter about it at Kinko's.... made 400 copies and mailed them to random addresses in the phone book.

Interview of her here:
