Young people very clearly have the most to lose should Trump be elected. Hopefully they will exercise their franchise.

Interestingly, for the two main presidential candidates, polls show the largest gender gap in US history. Male voters show a slight preference for Trump while female voters showed a very strong and growing preference for Clinton. The polls may in one sense be flawed. Women may simply be demonstrating a strong aversion to Trump.
