The fact that Haaretz is even calling this a "super-party" shows something about today's Israeli politics, it's no longer about party politics. It's now personality politics. Parties forming around personalities is now the default. Likud has always tended towards strong eldership. Labour is in recent years malleable to its leaders personality. Shas too. Yisrael Beitenu is used interchangeably with Lieberman. Barak followed Liberman's approach. Kadima formed around Sharon, so its got that in its DNA. When Lapid entered politics the only natural path was to form his own party.
