David Graham noted an unfortunate truism of the 2000s: The Democrats Are Now America’s Conservative Party. He's not attempting an actual critique of the long devolution of the party, just noting that the Dems are now the protector of the status quo. He never mentions characters like Joe Lieberman, Kyrsten Sinema, Joe Manchin... Instead, he makes a lazy, static argument that Dems accomplished so much progressive policy that now they want to hold onto it, which means they're conservatives.
