Perhaps, but it seems like a way out of this mess.
A unity government would be more feasible if PM was off the table.
That seems logical, and was the reason for the initial enactment.
However, no system is perfect, and the pendulum swings.
The other problem is that deep down, people know that there is no 'solution' to the conflict with the "Palestinians", or with the Jihadists (of various flavors). So the geopolitical options range from a delusional (but rooted in aspirations) attitude of unilateral concessions and withdrawals (an interesting video of what might have been the last meeting between Shimon Peres and R' Ovadia Yosef, with the former trying to convince the latter to support one of his delusional solutions, has recently surfaced), through the pragmatic and long horizon approach of Netanyahu of managing the situation locally, while getting regional focus away from the "Palestinians", or better yet rejecting their issue as a pan-Arabian one, to the extreme Zionist attitude of forcefully crushing any "Palestinian" aspirations.
This has just brought about the so-called "center left" B&W party, that doesn't really offer much of an alternative to Netanyahu's methods (though with less experience and talent). They have folded into their ranks some people who are proposing slightly different geopolitical approaches, but once reality hits, they will be no different (other than likely not being able to withstand major pressure from outside).
There hasn't been one poll in which Netanyahu hasn't trounced Gantz (or anyone else) in being seen fit to lead the country.
Lieberman did identify the one issue that ostensibly does highlight differences of approach, which is the anti religious establishment and laws vs pro such laws. Unfortunately, I think UTJ and Shas didn't use a correct strategy in this area. While they did energize their base, I think they should have put a lot more effort in reaching out to people outside of their base, who wouldn't vote for them, but try to get them to reject the Lieberman/Lapid approach.
The bottom line is, that we can write and suggest whatever we want, but:
Do I think Israeli politicians turn to DDF for suggestions? Absolutely not!
All I do here is report things as I see them and offer my analysis and/or point of view. Some like to call that
