It's an ongoing concern that so few voted, but with so little attention to the candidates platforms and ignorance about the issues, having a 90% voting populace might not be an improvement. Polls are becoming more suspect as phone #s go to mobile phones and compete with texts, videos and games. I wonder how they find a good sample of actual voters to poll.
The problems of maintaining a fair, honest government are hugely more complex since people's attention span has been divided between so many distractions and problematic media sources. (there are at any one time in the evening, 5-6 different right-wing cable TV channels available in my area..(the greater Wash.DC area) Fox news is famous, but one is consistently to the right of Fox! https://en.wikipedia.org/wiki/One_America_News_Network (and it is NOT a 'pay' channel in my list) They are a study in spin, distortion, lies, rhetorical blather and twisted logic. I look at it now & then to see where Trump is getting some of his latest ideas... He is said to be unhappy with Fox because they have a couple of hosts who actually try to see the truth and don't toe the party line.

You see? It really takes time and more effort than many are willing to take to sort the truths from the half-truths from the blatant lies!
