Barak Obama has demonstrated repeatedly throughout his campaign that he is among the most cynical politicians we have seen in a long time. His message is Hope and Change. The only thing he really Hopes is that we are all too stupid to listen to what he is saying. The only thing he wants to Change is his status, from Senator to President.
His most recent demonstration of Hope is that he Hopes we will not notice that when confronted about his pastor's outrageous anti-americanism he claimed it was news to him. The reason he Hopes we won't notice is that a few days later when his original explanation became completely untenable he confessed to being aware of it, but said that he didn't agree with it.
His most recent manifestation of Change is the changing description of his grandmother's comments about being afraid of black men on the street. The recent Change differs in very important ways from his description of the same event in his autobiography. In that telling she was afraid of one black man who she felt threatened by because of his particular actions. Which is the truth? Who knows and it doesn't matter.
What does matter is that Obama is a liar with Clinton-like loyalty (see earlier posts) who is perfectly happy to try and further his political career by trashing his still living grandmother's reputation branding her as a racist. The grandmother, by the way, who was his primary parent and support, according to his autobiography, in his growing up years. Disgusting.
