>The better question to ask...what if Bernie had never run at all, and Hillary had no competition throughout the whole primary?
With the Bruising primary Trump had? Probably a Hillary win. Trump’s biggest weakness was always the lack of full support from the GOP. I’ve never seen a party so dedicated to screwing themselves over.
Impossible to say, of course, that election would have had much different dynamics. But I suspect that Bernie Sanders would have lost worse than Hillary, his appeal was mostly to the far left and he would not have had the support of some of the powerful well-heeled establishment people who kept the tottering Clinton campaign from collapsing under the weight of its inherent absurdity.
I don’t think there would have been the mid-October diversion into Trump’s sex-related comments and the innuendo (largely unproven), Sanders would not have been given those openings, and frankly I don’t think he would have been that interested in pursuing it.
We will never know, but I suspect Trump would have won a few more states and the popular vote (please don’t bombard me with the standard but he did anyway stuff, I don’t have any way of investigating that, and it may be right).
