On Halloween there are always the requisite witches, pirates and rock stars. But with the general election days away, we’re guaranteed a few glimpses of political personalities. Not long ago, I heard a tap on my office door and there stood Obama, at least from the neck up, courtesy of an amazingly realistic mask. My daughter’s boyfriend has had a ball with that one. I threatened to take the broom to him if he tries to go vote while wearing that mask. A West Hollywood (Calif.) man hung an effigy of Palin from his chimney, perhaps the most tasteless and biased Halloween display this year.
