They’re not questioning him for the same reason questions about Biden’s fitness were brushed aside until the debate; no one’s actually listening to the old guy right now. For Biden, this was because his team was carefully controlling his public appearances. For Trump, it’s because no one goes to his rallies except his supporters, and they’re obviously not going to question him. Most people get the headlines and clips of his most outrageous statements, but almost all of them (myself included) would rather bash our own heads in with a crowbar than sit through one of his rambling, racist speeches.

At the debate, a large portion of the population is going to sit down and listen to Trump speak, and this time, his opponent won’t be an even older, even more incoherent man. If that doesn’t lead to questions about his fitness or mental state, then I will be concerned. But right now, the fact that no one is paying attention to Trump’s mental decline makes sense to me.
