My son in college says most of his friends want Bernie first and Trump second.
My daughter is the same way. She will be just barely too young to vote in November but some of her friends will be old enough. Both she and that say it is Sanders (first) and Trump (second). They do not want Hillary.
Of course they are all idealistic about Sanders, but they are very young and have time to mature. At least they are smart enough to understand that Hillary would be a very bad choice. This gives me hope.
