and their idiotic "I'm not voting for the lesser of two evils" rationale definitely played a role.

Also, let's give Bernie Sanders credit for half-heartedly dropping out of the race a full two months later than he should have, giving young impressionable voters a false sense of hope that he'd win. Their disillusionment was heard loud and clear on election day.

disappointment and resentment.

You have to assign more to the candidate. It was their job to address those other realities of politics. Well, except for the whole Russian thing. But I do think that the DNC and most democrats didn't acknowledge the challenge of a party getting a "third term".

given the bizarre nature of the race.

She rocked the debates, and was solid throughout. Clearly there were missteps at the end though.

I think they put too much stock in the polls, which were definitely way off.

She was in serious trouble from the beginning, which is why Bernie became such a threat to her. Yes, there were many mistakes made, the real question is could she have run a "good enough" campaign to win. Considering that "third terms" are very hard, one wonders if she could have done anything.

Just look at their slogans. Hers suggested that things were good and we needed to keep moving in the same direction. He suggested things were "bad" and we needed to change directions. She got the majority of the support. Unfortunately, the people that decided the election were people who thought that we were going in the wrong direction. And really, looking from their point of view, one can understand their frustrations. Conversely, there is no way she could have address their concerns in a meaningful way during the campaign. First she would have lost much of the support she did have (which was a majority) and second, these people where not going to accept someone with such a long history of involvement at the national level. Again, a minority of the population by a long stretch, and even a minority of some of the key demographics. Unfortunately, they were spread "just right" (which is why some people are suspicious that there was someone doing the spreading).

This is particularly frustrating to me because I've been concerned about this for several election cycles, that someone in the GOP would figure out that the democrats had lost much of the blue collar vote. I just never thought it would be Vladimir Trump.

being so wrong. Otherwise, they would have had a different strategy. But the whole thing was a complex moving machine and every little thing factored.

Obviously they were over-confident, and I suspect they, like I always did, thought Trump was unelectable as president.

He doesn't get credit for being a basic troll that they keep feeding.

but he did know how to manipulate them, so have to give him some credit.

Bernie got over it, some of his voters never did.

A Russian attack is to be expected

McConnell is a fucking traitor

the report.

I'm afraid the votes she needed to get, she wasn't going to get. Trump basically was right. He could shoot someone on Park Avenue and they'd still vote for him. The report might have increased her popular vote margin, by getting more votes in states she already won, or states where it still wouldn't have helped her win anyway. But I suspect in WI, MI, and PA, it wouldn't have changed anything.

I think reasonable people can debate the percentages you used for each category, but you have listed all the main ones.

I would add the electorate's general distaste for having one family too involved in the levers of power. There was backlash against Jeb Bush for this reason. Clinton faced some of the same backlash.

although I know some people did not want to see Bill back in the WH.

Thanks

Problem is does that same electorate even SEE or understand or grasp that you now have the tRump Crime Mob Family in there on steroids, and also involved with and are pro-RUSSIA up to their eyeballs.

tRump Crime Mob family (With an assist from their buddies the Russians).

whoops

It's a collection of things. But you can separate them into "Things we could have handled, things completely out of control" and I think you can collect enough of the first that this election could have been won.

EMAILS!!!

If I was to use the same list of reasons you did, I would have it similarly but with a couple minor differences of percentage:

I would have it as 25%, 10%, 20%, 10%, 5%, 30%

Without Donnie receiving 80% of the coverage, and without the Hillary coverage being nearly all negative, none of the other factors matter. In fact, many of the other factors are actually subsets of the biased media factor.

The media should never have presented Donnie as a viable candidate. He should have been covered like Gary Johnson. That said, had they been merely 50-50, Hillary would have won handily, even with the other crap.

Notice how Hillary had a nice lead after the conventions and after each debate? Those were the only times the media was remotely fair.

warmonger, poor businessman, liar, and worse., nothing the media could have done would have made a difference. People want an easy scapegoat, but I do not believe the media helped Trump. His ignorance, racism, white wingish leanings, etc., won it for him. That's what the people who vote in the key states wanted. Had Trump lost, the white wingers would have blamed the media. It ain't the media.

Seeing as HRC won the popular vote by a wide margin. The rest is just a collection of shiny objects the MSM wants us to obsess over. "Them's the rules!", all the pundits shout, while partisans toss ballots into a deep, dark hole.

Same as them relentlessly telling us the reason we're so poor is because we aren't clever, beautiful, talented, or just plain lucky enough, to ever be in their class.

And why? Because the Bible tells us so...

The Clinton's have always had a superior get out the vote ground game. It never helps if your base turns out to vote in blue states and their votes are changed electronically to trump.
Remember, Trump campaign stops in the end were reported as unstructured. Many said it looked like "Trump was trying to throw spaghetti at the wall" trying to figure a path to 270.

I think the sexism of most Trump supporters goes without saying. Did anyone vote against her just because of this?

I've seen it fronted as a reason. It seems small compared to your list. Maybe 1%?
