If I had to look for a big price, I still think there's value in Nikki Haley at about 100/1
Your bet is that Trump doesn't make it to 2020, or that for what ever reason (probably a backroom deal in return for immunity) agrees not to run. What price on either? Difficult to say, but if he fails to jump off, then Haley is head and shoulders above the opposition in the GOP right now. It's a question of trying to discount his price of not making it to the gate, and then taking a view as to what her price would be
