Nir Barkat will finish in 24th place, the last realistic slot for a candidate on the national list.
But—
Netanyahu has a long history of dealing with candidates he considers problematic who end up in the last realistic slot. In 2009, he came up with an interpretation to push Feiglin out of that spot.
Now, for example, he could reserve that slot for New Hope member Michel Buskila, thereby pushing Barkat down to 32nd place.
This isn’t the U.S. Constitution; it’s the primary election rulebook.
