Intrepid, he is not "going down to their level". He is the one who set a reprehensibly low level  of civility, maturity and responsible discourse, fanned its flames among his supporters and continues to be the biggest whiner and hypocrit. He threw mud and lies at Clinton, non-stop, and then has the temerity to accuse  his critics of "not being nice" to him. No wonder in an interview included in a Passionate Eye documentary tracing the history of his own, as well as Clinton's,  upbringing and career, he admitted that he wasn't given to self-reflection because he was afraid that if he looked at himself too closely, he wouldn't like what he saw.
