As a “PS” to my first post - I know many, including some family members that are typically liberal/moderate who are DYING to vote for someone from the GOP but won’t vote for Trump or Cruz. They like Rubio.
But the point being, there are lots of people out there waiting to “defect” and just like they won’t vote Trump or Cruz, they are not willing to vote Clinton or Sanders.
your family reminds me of those who want to escape the hellholes in the North and move South but then want the place they move to become like the place they moved from in the North.
