Maybe replace him with Tulsi Gabbard?
Person of color, combat veteran, professes Hinduism, reasonably intelligent, she presses more buttons than teenage pranksters on a skyscraper elevator. Add to that, she is vestigially conservative (after a fashion), and just a teensy smidgen pro-life (ditto). Two women on the ticket? Many people would do the mother of all happy dances in the streets if that ticket won.
Too much to hope for, but interesting to contemplate.
