They're the same age group that protested at great risk to end the War in Vietnam. They're the same age as the Mizzouri football players who boycotted the football game to stand up for BlackLivesMatter and brought down a University President and a University Chancellor. They're the same age as all the Berniei Sanders young people who are sending him like rocket over Hillary Clinton ... in Iowa. They're the same age as my great grandfather who volunteered as soon as he turned 18 to join the Union Army to fight and/or die to end slavery in the United States. They're the same age as my nephew who is 19, works and goes to college, and he knows as much or more about the candidates and issues than I do.

Based on that, their opinion is more than valid seems to me.
