If the Democrats aren't the party of fighting climate change, what are they going to run on in terms of what they actually want to do with government? Not the goals they want to achieve ("more affordability! less inequality!"), but the actual policies they want to implement? That was their major policy proposal, the one big bill they might want to adopt. What's left of comparable size as The Big Democratic Project if that goes away?

Welp, right now they're trying to pivot as far away from the Obama era's staple of Identity Politics and get back to a 21st century version of Hoover's "chicken in very pot, a car in every garage" messaging. They call it an "abundance agenda", whatever that means.

They're going to have to tack back to the center, hard: that means jettisoning Obama's foreign policy of Leading from Behind, stopping the flirtation with socialism, and a thorough rejection of the hard left identity politics they've been embracing. They're going to have to find a way to reconnect with unions and make them strong again but will need a lot of help from blue state governors to improve the business climates in their states (else any net new job creation happens in a Right to Work state with friendlier biz policies)...
