A low turn out is a sign of a candidate selection that can’t energize the voters. It doesn’t mean things are going well, it means the people don’t see a reason to bother.
A fourth of the country thinks they know what is really going on and have selected the better candidate.
A second fourth think they know what’s going on and have selected the poorer candidate.
A third fourth think they know what’s going on and reject both of them.
The final fourth realize that they don’t know what’s going on and they couldn’t care less.
