Look how in one day it has changed. (The Panel/Maeiv/ J. Post ) The Likud and Bayit Yehudi are really one bloc just as is Meretz and the Zionist Union. We rather need to look at how those 2 blocs are performing. Since the beginning of 2014 Likud + BY have fluctuated between 35 and 42 so 36 is bad. However ZU + Meretz have fluctuated between 27 and 31 therefore 30 is very good.
