> Because if you look at the entire history of presidents with the notable exception of Barack Obama, every president has been a geriatric white dude.
That's only true for an incredibly expansive definition of geriatric: Teddy Roosevelt was 42, Kennedy 43, Obama and Grant 46, etc. By a commom conventional standard of "geriatric” in general use (65+), only Buchanan, Harrison, Reagan, Trump, and Biden qualify at the start of their first term, and only 16 total would at the end of their last term.
> So, when compared with the younger black/indian woman
Harris was closer to (but still older than) both the mean and median age at start of term for a President than Trump was (even if you compared her in 2024 to Trump when elected in 2016). Gender and age, sure, but the whole geriatric thing as a long-term bias evident across the whole list of Presidents is unjustified (there's probably a decent argument that the current electorate has a geriatric bias, but its not a long-term historical one.)
