Meretz launched a campaign to attract left-wing voters to their party, using Facebook and standing in inter-sections to spread their new slogan: "Your heart is on the left."

"Ahead of Rosh Hashana, the prime minister is trying to frighten the public on the topic of Iran," Meretz chairwoman Zehava Gal-On said on Sunday. "What is truly scary is that our lives are in the hands of people we don't trust."

According to polls sponsored by Meretz, 18 percent of voters share opinions with the party's platform. As such, the membership drive, which began on Thursday, is meant to "bring people on the left back home," Meretz spokeswoman Hamutal Cohen explained.
