In descending order of likelihood:

1) No one

Unless Kristol actually has Romney or an incumbent Senator/Governor (and the fact that we're down to random House people being bantered about shows this probably isn't the case), he needs to face that Gary Johnson, while not as interventionist as him, is much closer to his views than Clinton or Trump and is eminently qualified to be President.
