Interesting question. Likud party won 40 seats, running on a platform against supporting evacuation of territories. But in the new elections, there is a chance Labor will be elected with a number of seats, which will allow it to form a coalition.
This could occur with some rightwing voters stopping to support the Likud, which has now adopted leftist policies, and move to support real rightwing parties. But these parties never get more then 20 seats, each.
