Of course, the whole population of any state isn’t eligible to vote. In 2008, which was similar to 2016 in that there is no incumbent, about 25-30% of eligible voters caucused for either Democrats or Republicans.

That seems like a more reasonable number in an apathetic country.
4% still sounds really low to me.
