"NBC New York asked Palin about the significance just as she board her bus outside Fox Newschannel to head off to Boston. Today is the 44th anniversary of Jerusalem being reunited, she said. We want to call attention to that.
The pendant is in every photo she took with fans and supporters and can be seen in every sound-bite captured by television crews."
