In my opinion, it's very simple. I became a one issue voter after one of the candidates tried to obstruct the process (violently), the last time. That's antithetical to America. It's ironic because it's the type of thing that happens in the "shithole countries" that we're so focused on keeping out (I say this as a person who thinks immigration reform with strong structure is long needed).

Rewarding Trump by giving him the keys is stupid if you can even muster the courage to say you believe in anything America stands for.
