I'm glad Sanders brought up the point of the SCOTUS, for all the people who feel like they can just sit this one out because what does it matter anyway? The next president will be around for four years. The judges selected by the next president will be around for that much longer than that. And that most certainly will have implications for the target populations that will be affected by future rulings.
For me personally, Trump selected Mike Pence for a running mate, threw together a who's who of anti-gay mouthpieces for an advisory board, will overturn marriage equality, and promotes conversion "therapy". And that is just not acceptable, now or ever. I applaud the Republican delegates who attempted to speak out about how inadvisable this is and how it is holding the party back, but sadly, it fell on deaf ears.
