Israeli political parties change like some people change TV channels ... LOL ...
Zionist Union Party
http://en.wikipedia.org/wiki/Zionist_Union
It is the combination of two former and existing parties in Israel. The Arab parties did the same thing ... :-) ...
Technically it’s just an electoral alliance, a joint ticket. The parties remain seperate entities.
Tipsy Livini’s party “Hatnuah” translates as “The Movement”, “the bowel movement”?
