I am wondering how the young women were chosen for this. Some for Clinton, some for Trump, a couple of undecideds. 

How representative is this group?  It's obviously too small to indicate anything at all.  But since the exercise was undertaken, choosing a sampling of young women from diverse racial, ethnic, and educational backgrounds might be at least slightly enlightening. 

Do they all have similar educational backgrounds? 

  An obvious problem is that there is not a single African-American, nor Asian, nor other minority, unless Ms. Ramos is Latina.   Nor was there a Muslim woman as far as I can tell.
