What if I told you (cue the Morpheus meme), that people consuming the "fake news" don't care that it's fake? It's called confirmation bias and winning. Education isn't going to solve this issue, you can't forcibly educate people nor can you change their core "values" and their determination to be "right".

The only "education" that I can envision working is quantifying the real-world-impact of their votes on the personal level. Ex: Your health insurance was cancelled? The representative you voted for caused that. This unfortunately is normally executed with a partisan goal, however should be applied as a public service to all Americans.
