Prometheus 6

I decided I'd say something like, "My opponent has chosen to campaign in a negative fashion, and many people, even among my supporters, say I need to respond in like fashion. That I insist on talking you you all like adults is seen as a weakness. It is not. It is a choice. It is a kindness, which all too many people mistake for weakness."

"To prove it is a choice, for the next two weeks we are going to campaign against Mrs. Clinton the way she campaigns against us, just to show we can. Then we're going to return to campaigning as we should, as America needs both of us to. Hopefully when Mrs. Clinton sees the choices we've made she will join us in elevating the discussion to a true consideration of the issues that are important to America."

Some shit like that. And I'd do it just like that.
