Some of them are Livni die hards who were not happy she lost the primary to Mofaz who now welcome the fact she has formed a new party and so are rushing to join her. Others can see the good ship Kadima is sinking so rather come election day discover they have lost their seat they want to jump overboard now on the grounds its they just planned to quit politics anyway so they can save face. If Labor had a more professional less ammeter socialist image then some of those who want to jump ship would have gone to Labor rather than Livni. Time to ditch Shelly, Stav, Micheli and Mitzna in favour of somebody that looks like the county is safe in my hands.
