That's a very good point. I love seeing how many people on HN assume that, if everyone had access to the knowledge they have, everyone would vote D. Which isn't true and which is precisely the reason why R won. Furthermore, Pew Research has shown a lead of 9 points for D in college-educated population, which isn't very impressive given the dominance of liberalism at colleges.

Overall, it's a hard problem.
