The fact that you think issues immigration (and healthcare, etc.) are dwarfed in importance by the stylistic differences between the candidates says more about your utter callousness and the sheltered bubble you live in than the absence of substantive differences between the candidates.
One candidate wanted to repeal the ACA and replace it with something else TBD, the other wanted to keep it. Unfortunately, the ACA is not going to solve this country's health care problems. So a candidate's position on it largely doesn't matter.
(Ironically, the current administration struck the penalty for not carrying health insurance, reducing health care costs for some of the poorest)
Compare this approach to Sanders, who wanted to extend Medicare to everyone. That is a clearly different policy approach.
Going back to the hot dog stand analogy, Sanders wasn't only far from the middle of the beach. He was on top of a cliff on the opposite end of the island.
That's what a policy difference looks like to me.
I'm not saying that health care and immigration don't matter. I'm saying the party nominees of 2016 were like two hot dog stands located within spitting distance of each other on the beach.
