Presumably similar to what happens today if the Pres and VP are both removed at the same time. Speaker of the House, pres pro-tem of the Senate, Secretary of State, and so on.
I might tweak it a bit, though, and have the Pres and at least some of the cabinet be declared on the ballot—instead of VP, include Sec of State, Treasury, and Defense on the ballot. If we want to keep “president appoints their successor” functionality, move sec of state above speaker of the house.
