Opi- as far as Haley being quiet, I saw an interview with her where she said she has offered to campaign with Trump and act as a surrogate, but he has not responded to her.

Makes no sense, but it's Trump. She could have helped him with women particularly. The question of why he wasn't accepting her offer is what prompted Cuban to make his statement about Trump not wanting to be around intelligent women, because he was intimidated by Halley.
