Who is the most to blame for Hillary Clinton's loss?

[Pollster]

I'm going to leave out Russia since the true impact they had is difficult to measure.

1. The electoral college.
This archaic system has now elected two leaders in the past 20 years that the country did not want. This continues to be evidenced by the tanking approval ratings both faced.

2. The Clinton campaign.
Blaming HRC alone for her loss when very few strategic decisions were actually made by her is too harsh. Mook's strategies were well-intentioned but ill-executed, and his reliance on modeling even when the data from the ground didn't match up is inexcusable.

3. James Comey
Comey's activity in the final weeks of the campaign swung undecided voters towards Trump, especially in key areas. Comey will likely go down in history as the man who began the end of the Trump presidency but it must be remembered that he also helped to cause it.

4. Voter suppression laws.
In many states with strict voter suppression laws, especially those with high AA populations, Trump received fewer votes than Romney but managed to win due to massive drop-offs from Obama to Clinton. Lessened enthusiasm is certainly a factor but to ignore the impact of voter suppression laws would be a mistake.

5. Bernie Sanders
Sanders' campaign made HRC's platform better and energized voters, but his refusal to accept defeat when it was evident early on was far more catastrophic than it was played out to be. Every day from then on, he made HRC weaker. His nonsensical assertions that the primary was rigged despite the fact that one of his top advisors helped craft the rules (and the media's refusal to call his BS on this) should and hopefully will be vilified in history as much as the coverage of the emails.

6. Media
As briefly mentioned above, the media allowed virtually all of HRC's opponents to run amock and gave Trump especially billions of dollars in free airtime while covering all of her admitted missteps and gaffes acutely and in the harshest possible terms.
