I have yet to hear what a single one of those emails said that made Hillary Clinton look bad
They show that they colluded with the DNC to "un-level" the playing field against Sanders (John Lewis and the CBC were involved in this by the looks of things). Apparently, Clinton thought she had the right to decide who the DNC candidate should be (her) and not the electorate.
Which I consider to be pathetic but should that count towards electing Trump? The people most likely to be incensed about this were Bernie Sander's supporters. They may have hated Hillary's guts but they're not likely to have voted for Trump even as a protest vote.
Also, the campaign was colluding with journalists to get questions in advance. And that she was calculating and giving a different message in private than her public position.
Let's go through this thought experiment:
You have a choice between electing Mussolini or Hillary. Should one justify what happens after Mussolini wins by saying that Hillary was a poor candidate? Would you consider Hillary anywhere near as bad as Trump? Who is the lesser of two evils? Mussolini (=Trump) or Hillary?
Bottom line, they are not equal. Hillary was a mediocrity who would have kept the status quo; no change. Trump is nothing but desolation.
