Who Are These People?

if it's really true that the election is in the hands of the "undecided" voter, our democracy is in trouble. How could a person still be undecided at this point? Who are these people? Is the fate of our country and the world really in the hands of the dumbest and least informed people in the country? Or, is the fate of our country and the world in the hands of a small group of people who take the time to gather all of the facts and make an informed decision? I fear the former, but I hope it's the latter.
