Trump needs Elise Stefanik.
Huckabee Sanders would be my choice. She has more common sense than anyone I can think of. Actually, Tulsi Gabbard might bring in some demonrats votes.
This is not aimed at you, but the commentariat out there: What's the deal with assuming we must have a chick VP? That increases the odds of a female President, which is an idea that no one dares criticize, but no one actually would like--except our enemies.
Europe has had queens and female Prime Ministers, but those are very different from Presidents. A queen represents a nation as a function of her family of origin. Prime Ministers are, legally speaking, the leaders of their own political parties first and their nations secondarily.
A US President must stand for the whole nation and give himself entirely to it. That's not appropriate, or even possible for a woman, because a woman's strength, grandeur, and sacredness derive from the fact that she stands first for her family.
By contrast, a man who leads an army or the American nation leaves behind his family, his party, and his state of origin. He pledges to put his country above all things, and to sacrifice his life for it, if necessary. He is a successor to the signers of the Declaration of Independence--without which America would not exist. They pledged "our lives, our fortunes, and our sacred honor."
