Democrats make ads all the time about how they are willing to work across the aisle with the opposing party. (I know some Republicans do, too, but it’s not as prominent a thing on the right.) The notion is worn like a badge of honor, as if Democrats need to show how not Democratic they are. For instance, in this election cycle, we have Elissa Slotkin in Michigan saying, “I refuse to let partisan politics hold this country back.” Senator Maggie Hassan goes even further, bragging, “I took on members of my own party” on a gas tax holiday. President Biden campaigned in 2020 on his supposed ability to work with Republicans (even if he’s learned how ludicrous a notion that is).
And while the realities of getting legislation passed sometimes forces cooperation, to insist that you as a Democrat need buy-in from the other side in order to justify your position makes it seem like you’re apologizing for being a Democrat. The whole idea is a comforting lie, affirming a fictional tale of the two parties who can put aside differences for the good of the country. Mostly, it forces Democrats to agree to negotiate with people who are insane extremists and pretend like their positions aren’t so.
