Similar to Anti Trump... I believe Pro Trumpers are at this point harming the fight against progressivism by leaving that as the point of contention and not picking someone else to lead the fight. In Israel OTOH, IMO there is no easy pick to replace Bibi in that role.
Bibi is a rare kind of person with multiple talents and abilities converging.
There are some (potentially) great people with great talents and abilities, but no one that I can see with everything he has in one person (a very thick skin being an important quality, along with the right type of conviction).
Even in the US, you might have some great people, but one really needs a very thick skin and strong convictions in order to do the right thing. For example: I think Mike Pence has great conviction, but I don't think he has the character and charisma for the job. Nikki Haley seems promising, but is her skin thick enough?
