For those unaware, the economist ran this [1] image after Biden’s historically disastrous debate in ‘24 (as a result of Biden’s age based senility being on full display after months of party and media complicity).

(Not just The Economist, mind; almost every MSM outlet has mostly ignored Trump's mental inadequacy from the moment he came down the escalator. If they'd reported on it honestly from the start, there would be no Trump presidencies.)
Biden was clearly experiencing major cognitive decline over the course of his presidency. Trump was/is not. I've not seen any serious argument or evidence that Trump has experienced a cognitive decline, whereas the evidence for Biden's decline was his every public appearance. Are you being facetious, or is this your actual belief? If so, what is the evidence?
I don't know what to tell you if you can't see it from literally every public appearance he makes.
