If left wing voters stay home, the right wing will simply get stronger and stronger, because that is the way our electoral system works. The choice is not brilliant, but opting out simply means that right wing parties get more of the power. The bottom line is who turns out on election day. Look at Jerusalem. If the Palestinians in East Jerusalem decided to field candidates and vote for them in order to get a fair slice of the city budget in exchange for the city taxes they pay, they would have a large number of the seats in city hall and the right wing would have a much more difficult time giving all that money to settlers in the CIty of David. Not voting means strengthening one's rivals. Nobody should forget this.
