The latest postmortem involves Hillary Clinton's loss of the traditionally safe Democratic state of Michigan, and it is excellent. From The Politico:
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.
Michigan organizers were shocked. It was the latest case of Brooklyn ignoring on-the-ground intel and pleas for help in a race that they felt slipping away at the end.
“They believed they were more experienced, which they were. They believed they were smarter, which they weren’t,” said Donnie Fowler, who was consulting for the Democratic National Committee during the final months of the campaign. “They believed they had better information, which they didn’t.”
Flip Michigan and leave the rest of the map, and Trump is still president-elect. But to people who worked in that state and others, how Clinton won the popular vote by 2.8 million votes and lost by 100,000 in states that could have made her president has everything to do with what happened in Michigan. Trump won the state despite getting 30,000 fewer votes than George W. Bush did when he lost it in 2004.
COMMENT: Read the whole thing. It's worth it. American political history is filled with "sure things" who weren't, as the late President Dewey learned. And the sure things were products of ego and a sense of superiority. A description of Hillary and her troops.
