Paul Krugman lays out the central conundrum facing Democrats, specifically with regards to how to fight back against Trump's predation of the social safety net, notably Social Security. The "tear-your-hair-out" moment for Democrats is that this plutocratic, failson slumlord has managed to position himself as the champion of working Americans.
The "Progressive" wing of the Democratic Party has claimed this is because Democrats abandoned the working class for siren song of neoliberal economics (mostly this criticism is applied to Bill Clinton). This argument founders on the reality that Clinton expanded healthcare to children (CHIPS) and then Obama created the largest expansion in wealth redistribution since LBJ. Then, Trump tried to kill ACA, but everyone seems to have forgotten that this is who he is.
The reality seems, to me, to be that Democrats embrace of LGBTQ rights and immigration reform (rather than immigration demagoguery) has made them seem like the party of, as James Carville put it, faculty lounge politics. Then again, LGBTQ rights are, in fact, important. "Elites" - at least culturally - have indeed become part of the base of the Democratic party; college educated professionals are a huge part of their voting bloc.
This has not led to Democratic abandonment of income redistribution. What you have on the Republican side is a weird wave of support, with people making between $50,000 and $100,000 seeming to support Trump and billionaires bankrolling him and staffing his administration. The result is that the "working people's champion" has people like Commerce Secretary Howard Lutnick saying that his mom wouldn't miss her Social Security check. Yes, that's probably true, since her son is a literal billionaire.
Both Krugman and Richardson note that Republicans used to believe in some form of social safety net - though I think Teddy Roosevelt's embrace of universal health care probably came AFTER his presidency when he ran as the Progressive Party candidate in 1912. Eisenhower and Nixon's support for some redistribution and government oversight of the economy was a nod to political reality. Reagan overturned all that, even if even Reagan wasn't going to go after Social Security. It was the rise of the Gingrich Republican who wanted to overturn the New Deal that led to Bush trying to privatize Social Security and Trump trying to end the ACA.
All of this is a long way of saying the Republican Party is still the party of Newt Gingrich's extremism; they still want to gut the social safety net. However, precisely because they have tried and failed to do so has created in tens of millions of voters the idea that nothing bad will happen to MY government programs, just those that go to the "undeserving".
This is how you get the incredibly frustrating dynamic of this past election. Trumpists write Project 2025 which is as radical a document as I can remember in 125 years of American history, maybe all the way back to the Civil War. Project 2025 - when explained to voters - is really, really unpopular, so Trump says he has no idea what Project 2025 is and the press seems to believe him. (No, I don't know why Democrats stopped hammering him on the contents of Project 2025; that was the biggest tactical misstep, arguably even bigger than Biden not stepping aside.)
Donald Trump is a compulsive liar. He has absolutely zero regard for the truth. Yet, somehow, his agenda - which was right there in black and white - was not scrutinized by voters. It was precisely those low information voters who returned him to the White House.
The post-election postmortems all seem to avoid this point. Trump's agenda was unpopular, yet voters were more or less not exposed to it or they simply believed his lies about Project 2025 and his promise to be a "dictator on day one." There is not a suite of policy papers that will undo this dynamic. People aren't flocking to Bernie and AOC's rallies because they believe in the Green New Deal, they are going because those two are actually "fighting" in visible ways.
This is why right now the central tentpole of Democratic strategy seems to be to get out of the way of Trump's mistakes. Let him and Musk gut the government. Especially if it's Social Security being gutted, that could have a major impact on actual voters.
The reality is that the only lever Democrats have right now is that what Trump is doing is illegal and - as Jamelle Bouie so concisely puts it - anti-constitutional and the courts largely agree. They can do nothing in the Senate and less than nothing in the House. In fundamental ways, they are waiting for Trump and Musk to crash the government in ways that even those low information voters can't ignore. Trump thinks he can re-write reality, but he can't. The worry has to be that Trump somehow makes things bad but not so bad that you get a massive revolt from the electorate in 2026.
That, unfortunately, is not a proactive plan. The Bernie/AOC rallies and the empty chair townhalls are a nice performative step, but they don't yet reach the level of a plan.
