No, she wouldn't. Without the Comey letter she would have won.
But without the Bernie or Bust crowd she would have won.
Without the help from Putin for Trump she would have won.
Without sexism she would have won.
Without her idiotic failure to campaign in the Rust Belt states she would have won.
Without her nincompoop of a campaign manager she would have won.
Without the racism and xenophobia of Trump supporters she would have won.
Without the disillusionment of the Rust Belt blue collar former Democrat workers she would have won.
Without her unforced errors such as saying to Wall Street investors that she had one opinion for them, another for public consumption shw would have won.
Without Wikileaks she would have won.
Without the enthusiasm gap in her campaign vs. Trump's she would have won.
You left one out. Her decision to be above it all and refusing to actually fight back. I figured that one out when they were debating and the Jackass was wandering around her so he could get up close and personal and threatening (and she allowed that to happen!) by the time they were through demonizing her there were people believing she murdered people, ran sex slave operations out of Pizza parlors, etc.
I suspect Biden might find himself in the same position unless he actually starts to fight back. He might start by asking CNN and MSNBC to give him, at least, 2 hours of free exposure every week as they are now gift Jackass Trump with 2 hours a day!
Hell, even 1 hour a week would be better than what he has now which is, basically, nothing!
