JERUSALEM (JTA) — American comedian Sarah Silverman called on Israeli voters to cast their ballots for the left-wing Meretz Party.

Silverman tweeted her appeal early Wednesday.

“ISRAEL! If you are a Meretz supporter you NEED to VOTE MARCH 17. Every vote counts. If you don’t vote, you can’t complain,” she tweeted.

Silverman also backed Meretz in a tweet in November 2012, in advance of the January 2013 elections.

Silverman’s sister, Rabbi Susan Silverman, who lives in Israel, reportedly is number 20 on the Meretz Party’s candidates list, which is not a realistic position to garner a seat in the Knesset. Meretz Party head Zahava Gal-On reportedly is a friend of the rabbis, according to Israeli media.

Meretz on Tuesday launched a new campaign in which it acknowledges that it might not get enough votes to pass the election threshold to get into the next Knesset. Parties must garner at least four seats in order to be part of the next Knesset. The lost votes reportedly are going mostly to the Zionist Union, a collaboration of the Labor Party led by Isaac Herzog and HaTnuah headed by Tzipi Livni.
