18-24 year olds are always anti-establishment, which happens to be Democrat right now. They're not actually going to vote for some Republican splooge who reminds them of their high school principal.
To be fail, Hillary reminds me of an overly strict librarian.
Yes, Hillary's appeal to young people is a HUGE question mark for Dems and not promising... in fact I count on young people participation cratering if it's Hillary vs. virtually any Republican.
Yup. I agree with what you said before. The youngs are not swinging en masse to the GOP, but the bloom is of the rose with the Democrats. They might still show up to vote out Big Bad GOP Presidential Candidate, but they won't show up to vote out their GOP congressman in a mid term.
