And there is an interesting argument that most modern presidential approvals have more to do with the media environment and better visibility on just how bad their policies are.

[1] I'd argue better than that loser Bush who was probably the worst president in modern US history and who's polling showed it, but for the sake of keeping things simple.
I think you can go further, the ratings are also heavily tied to things like gasoline prices and the overall economy, and generally things the president has little control over. So actually not much to do with their policies at all. I think Trump knows this and it's why he's done some strategically stupid things to the US fossil fuel industry in order to tactically bring down gasoline prices to juice his ratings.
This likely also explains the 2024 election, because it happened in the context of vast sums of money being sucked out of the economy as the fed tried to fight inflation. Incumbents globally got an absolute thrashing that year regardless of what their actual policies were.
People have it in their heads that this is some bleeding heart, don't ruin the planet thing, but it's plain economics. Non-renewable energy is simply inferior, and will only become more so.
