How old is old enough to have a voice in our democracy?

Is 12 too young? Should there be a cap at 90? We asked our YouTube audience and the response was... hard to miss. Host Toussaint Morrison, producer Josef Lorenzo, Teresa Nelson of the ACLU and almost 12-year-old Brianna Smith weigh in on the question, should 12-year-olds be allowed to vote? We even tackled some of the MANY viewer comments.
