How has Netanyahu lasted so long. Even when parties stay in power a long time, I've found usually after a decade in power, people get tired of person. Of wealthy countries, I believe Mark Rutte in Netherlands only won who has been in power more than a decade and interestingly enough Netherlands like Israel is very fragmented in terms of parties.
I imagine, in addition to the fragmentation of Bibi’s opponents, it has something to do with Ariel Sharon having an incapacitating stroke at a most inopportune time and Ehud Olmert being criminally corrupt
and weak on national security in many ways—never a good thing to be in Israeli politics, obviously.
