Like you, I too do not believe Ms Doyle chose to quit, but rather, she either was fired or forced to resign by Hillary Clinton. Mrs. Clinton has always given me the impression that she thinks that she is  superior to others. In fact she is an opportunist, riding on the coattails of her husband, Bill, who, by the way was a poor president. Now that Clinton's staffers are aware of the way she operates, I would not be surprised if some of the key people in her staff jump ship.  If Hillary wins the presidency, all hell is going to break loose. I highly doubt that she will. As for Ms Doyle, I believe that she will prove to be a better person than Clinton and go on to a very brilliant future and career.
