Thats why they aren't just comparing each state just to the US average but to other countries.
There are 35/50 states on the graph, with 34 of them above the 2nd highest country (el Salvador).
This shows that even the US states that are lower than average are still higher than other countries.
The constant "there's a dang Cheeto in the white house!" comes with the implication that anyone who wasn't "the Cheeto" would be meaningfully different in the role.
Particularly in 2016 - 2020 the implication was Hillary, now it's Harris, as that's who he ran against.
Edit: It's a focus on the individual in the role rather than the system itself, despite vast evidence that the problems are long term and systemic. Whether the intention or not, it's undeniably a liberal defense of the broader system itself.
