David Roberts at Vox goes deep into the numbers, the graphs, and what everybody says about why Clinton lost and Trump won.  And he concludes…..

Turns out everything mattered

The most agonizing implication of the narrow loss is that everything mattered.

Every decision to hype Clinton’s emails. Comey’s extraordinary violation of precedent. WikiLeaks. Clinton’s Goldman Sachs speeches. Her refusal to dissociate from the Clinton Foundation. Her poor retail politics. Trump not releasing his tax returns. Mitch McConnell and Paul Ryan hiding out. Sanders tarnishing Clinton’s image among young people. Institutions standing by and doing nothing as Trump shredded democratic norms. The gamble that Trump’s misogyny and racism would render him unacceptable.

Fake news on Facebook. Epistemological bubbles. Elite self-absorption. Hot take after hot take delivered to the choir. Americans making the contest into a crass reality TV show fueled by Facebook memes. The press refusing to cover policy.

And whatever else you can name. The Electoral College turned on a 107,000-vote margin. All of it mattered. If you’re prone to haunting, crippling regret (luckily I don’t know anyone like that), that’s where you should focus your energy.

Yeah. Probably correct.

But that’s just one bit of one very long and entertaining article.  A must read for professional and amateur political scientists.
