It’s Israel. Parties come and go mostly based on personality. This might be Netanyahu’s last hurrah. Likud won’t survive without him. With Feiglin sitting out and Yachad losing out, there’s room for another Right party next election.
Minimum representation went from two seats to four seats this time. Maybe the minimum should be 10%, a theoretical dozen seats.
I shouldn’t comment on the spread, not knowing their system as well as I would need to.
I do understand your point though, and it was an interesting one.
I hadn’t given the party ‘life span’ consideration before, but the way you explained it makes sense.
