I think you need to read more of the sentence. It’s objectively good to everyone, even fiscal anti regulatory conservatives, to not have lead pipes. But to fiscal anti regulatory conservatives the method is antithetical to their dogma. So they will feel compelled to roll back while waving hands about how the goal is good the method is flawed etc. But since the goal is objectively good to all, almost everyone will just see “evil conservatives killing us for money.” In that sense, as I said, it’s a trap for the next conservative administration.

Calling it a trap implies malicious intention. Instead reality is that people are just trying to accomplish a good thing because it is a good thing. That Republicans may decide to be evil and shoot themselves in the foot with regressive policy doesn’t make doing good things a trap.

Oh if this were how political policies were created. Especially in the final year of a presidency they create an array of things that the “other guy” will likely repeal due to misalignment with their political ideology in their implementation if not their goal. Then they can call “gotcha” on the other guy if their opponent wins. Sometimes they do stuff like start messy military operations as they leave the White House, too. See Somalia and GB Sr
