The best way to insure the election of Clinton is to nominate Trump.  Indeed, even if he is not nominated, his positions have caused the candidates to say things which will almost guarantee she wins anyway.  Trump is, in fact, not a Republican and has no particular ideological foundation that matters.  He also was confused about the nuclear triad AFTER it was defined for him.  His personal conduct and advocacy of violent behavior should disqualify him from consideration by any serious political thinker.
