Hillary Clinton's presidential campaign was doomed not by Russia, or the FBI, or fake news, but by a never-ending cascade of terrible decisions by its top campaign staff in Brooklyn.

It wasn’t sexism, or racism, or the FBI, or fake news, or the Russians, which cost Hillary Clinton the presidential election. According to a blockbuster campaign dispatch published by Politico on Wednesday, sheer incompetence was the real cause of Clinton’s electoral implosion in November.

Clinton’s loss was caused not by one bad decision here or there, the Politico report shows, but by a cascade of mind-bogglingly stupid decisions made throughout the campaign.

For example, there was the time campaign surrogates were ordered to stay and campaign in Iowa, which Clinton lost by 10 points, instead of working to get out the vote for Clinton in Michigan:

Everybody could see Hillary Clinton was cooked in Iowa. So when, a week-and-a-half out, the Service Employees International Union started hearing anxiety out of Michigan, union officials decided to reroute their volunteers, giving a desperate team on the ground around Detroit some hope.



They started prepping meals and organizing hotel rooms.



SEIU — which had wanted to go to Michigan from the beginning, but been ordered not to — dialed Clinton’s top campaign aides to tell them about the new plan. According to several people familiar with the call, Brooklyn was furious.



Turn that bus around, the Clinton team ordered SEIU. Those volunteers needed to stay in Iowa to fool Donald Trump into competing there, not drive to Michigan, where the Democrat’s models projected a 5-point win through the morning of Election Day.

Then there was the time the campaign, instead of spending its cash in competitive states the candidate needed to win to clinch an electoral college victory, sent millions to the Democratic National Committee, which used the money to run up vote totals in uncompetitive states so Clinton would win the popular vote:

But there also were millions approved for transfer from Clinton’s campaign for use by the DNC — which, under a plan devised by Brazile to drum up urban turnout out of fear that Trump would win the popular vote while losing the electoral vote, got dumped into Chicago and New Orleans, far from anywhere that would have made a difference in the election.

There was also the time Clinton didn’t even bother to show up at a Michigan event for the United Auto Workers, a key union constituency on which Democrats traditionally rely for get-out-the-vote (GOTV) efforts throughout the Rust Belt:

Clinton never even stopped by a United Auto Workers union hall in Michigan, though a person involved with the campaign noted bitterly that the UAW flaked on GOTV commitments in the final days, and that AFSCME never even made any, despite months of appeals.

The Clinton campaign also completely ignored cries for last-second, all-hands-on-deck GOTV help in Michigan on election day. According to Politico, Brooklyn-based campaign staff waved off data showing massive shortfalls in urban turnout and insisted the Democrat would win the state by at least five points:

On the morning of Election Day, internal Clinton campaign numbers had her winning Michigan by 5 points. By 1 p.m., an aide on the ground called headquarters; the voter turnout tracking system they’d built themselves in defiance of orders — Brooklyn had told operatives in the state they didn’t care about those numbers, and specifically told them not to use any resources to get them — showed urban precincts down 25 percent. Maybe they should get worried, the Michigan operatives said.



Nope, they were told. She was going to win by 5. All Brooklyn’s data said so.

Clinton would eventually lose the state by 11,000 votes, less than one quarter of one percentage point of all votes cast in the state.

In the end, though, it appears that hubris may have been Hillary’s ultimate downfall. Hours before polls closed and long before returns began trickling in, Clinton’s top staffers weren’t scrambling for every last vote. Instead, they were busy measuring the Oval Office curtains and searching for champagne bottles to uncork to celebrate their historic victory.

“In at least one of the war rooms in New York, they’d already started celebratory drinking by the afternoon, according to a person there,” Politico reported. “Elsewhere, calls quietly went out that day to tell key people to get ready to be asked about joining transition teams.”

Oops.
