 From this distance I gather that overall in the US with those 3 
candidates Sanders would be the sincere big CW, and there would be quite
a few  Sanders>Trump and Trump>Sanders.  With similar media access 
Sanders would likely have been also the sincere plurality winner.

I think  shake-things-up versus more-of-the-same was more significant 
than the "feminist/masculinist axis".

On your hypothetical figures IRV and "plurality with runoff" would elect 
Clinton 49-48.

Clinton looks like the CW.
