The only reason they mention Rodham is because she used that and not Clinton as her last name for many years after she was married. She didn't change it to Clinton until it became necessary for reasons of political expediency. So she was known by many as Hillary Rodham and not Hillary Clinton. But none of the middle names of the other candidates are mentioned at all. I don't know the middle names of any of the other candidates. People are making a point of using Obama's middle name for the purpose of spreading hate.
