Most of them think Bernie would have given Trump a tougher race than Hillary. They’re probably right. She was an exceptionally bad candidate.
I know some Trump voters who would have voted for Bernie had he been the nominee. They see Bernie as “even more outside the establishment” than Trump. Those of us who pay attention know better than that, but yes, Trump definitely benefited by the fact that Hillary was an awful tone-deaf candidate. A real stiff.
Bernie would have beaten Trump.
