I just watched Hillary "apologise" for her tasteless reference to Bobby Kennedy's assassination. She said that she didn't intend it to be offensive and she was sorry if anyone took it that way (paraphrase). That isn't an apology, it's a defensive reaction.
The only favor she is doing for the Democratic party is to open the doors of the Augean stable, revealing the humongous pile of horse feces that has been choking the principles and spirit of freedom out of the party since, say, 1972, when the establishment Democrats decided to teach the DFH's that winning the nomination wasn't good enough to win their support. Can we learn the lesson: don't trust your interests to those who have consistently betrayed you for their own political advantage.
