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.
