A Washington Post article from exactly 7 years ago, this point in 2016, after Trump's first election:
Have Democrats learned their lesson? There’s reason for hope.
By Katrina vanden HeuvelNovember 7, 2017
In the run-up to the 2016 election, Sen. Charles E. Schumer (D-N.Y.) dismissed the possibility that Donald Trump's popularity with rural and working-class voters spelled trouble for the Democratic ticket. "For every blue-collar Democrat we lose in western Pennsylvania, we will pick up two moderate Republicans in the suburbs in Philadelphia," he proclaimed, reflecting the prevailing attitude within the party establishment. "And you can repeat that in Ohio and Illinois and Wisconsin."
One year after the election, it's not clear that Democrats have learned their lesson. Many have deluded themselves into believing that Russian interference, and not the party's abysmal failure to win over the working class, was the primary culprit in Hillary Clinton's crushing defeat. Clinton herself has pointed fingers at Sen. Bernie Sanders (I-Vt.) and former FBI director James B. Comey, while mocking former vice president Joe Biden's suggestion that her campaign did not offer a vision for the middle class. But even as Democratic leaders have cleared the wreckage and begun to rebuild, there has not been a full and honest reckoning with what actually happened in 2016 or how the party can avoid the same outcome in the 2018 midterms.
In the absence of an official inquiry, a group of Democratic and progressive activists last week published "Autopsy: The Democratic Party in Crisis." While the 33-page report covers a range of issues, it offers a particularly harsh indictment of the party's self-defeating attempts to simultaneously please its billionaire backers and the working-class voters who make up the Democratic base. "Corporate domination over the party's agenda — and, perhaps more importantly, the perception of corporate control over the party's agenda — rendered the Democrats' messaging on economic issues ideologically rudderless and resulted in a decline in support among working-class people across racial lines," the autopsy states. "We live in a time of unrest and justified cynicism towards those in power; Democrats will not win if they continue to bring a wonk knife to a populist gunfight." ...
If they hope to avoid a repeat of the bludgeoning they suffered in 2016, Democrats will have to work harder to establish a clear, compelling vision of what they are for beyond opposition to Trump. They have to build and expand a cross-class, cross-racial coalition of voters in every part of the country. They have to demonstrate, through action, that they care more about defending the interests of workers than rewarding big donors or winning over supposedly moderate Republicans who have burned them in the past. Trump’s plutocratic agenda is a massive betrayal of the working-class voters who once believed he would fight for them. But it would be a tragic mistake for Democrats to assume, as they did a year ago, that Trump’s shortcomings alone will carry them to victory.
Democrats did not change and history repeated itself.
What needs to change now?
