I mean even "educated" PhDs who "read a lot" are still stupid as fuck and cannot for the life of them realize that they are being swayed by propaganda so I think the problem goes way deeper than just basic reading comprehension
Actually now that I think about it, solving reading comprehension is a lot easier of a task than trying to un-brainwash these dumb "well-read Politics and Prose" liberals who drive around with NPR stickers on the back of their cars and laptops...
