I'm in my mid-20s and I'd like to believe you, that the younger generation was better informed and not so shallow in casting our votes as our elders, but I can't. Millennials may be able to navigate the internet more effectively than their parents and grandparents (and thus find multiple news sources, etc.), but they are proportionally just as negatively affected by the internet's faults. In my opinion, the whole "echo chamber" phenomenon was particularly bad among the youngest generation.

My peers and people younger than me surrounded themselves with pages, podcasts, and subreddits of people they agreed with, with very little lucidity about doing it. Dissent can be downvoted, banned, and unfollowed in a way that isn't possible in the real world. /r/the_donald is a great example of this, but so is /r/politics. Many Sanders supporters were voting for him for the same shallow demagoguery and circle-jerking you seem to put on old Trump supporters.

If the younger generation did anything more to battle misinformation than others, it was only due to their savvy with social media (the breeding ground of misinformation), not some superior critical thinking skills. I don't think that is due to a benefit of education at all.
