The Great Society legislation, brought to us by Lyndon Johnson (the Son Of Satan) and Patrick Daniel Moynihan, the original Guilty White Liberal from New York who felt that the 25% out-of-wedlock birth rate in the black community at the time was unacceptable. What they brought in replaced Daddy with a welfare check and doomed entire generations of black people to perpetual dependence on government to "do" for them. Think about the people in the Superdome after Katrina and Rachel Jeantel.
And why is Lyndon Johnson the Son Of Satan? The Great Society Legislation (find his quote about "those N-words are going to vote Democrat for 100 years now"), and the Gulf of Tonkin Incident, which led to the Gulf of Tonkin Resolution. Nobody died as a result of Watergate, but that was an enormous scandal. Gulf of Tonkin, just another day in Democrat politics as practiced by Lyndon Johnson.
For the double whammy of Vietnam and the Great Society, I have always regarded LBJ as the worst American president. But Obama is making a real run for his crown.
