In 2004, he founded the Jewish National Front, and headed its Knesset list in the 2006 elections. During the election campaign, Marzel called on the Israeli military to "carry out a targeted killing against (left-wing figure) Uri Avnery and his leftist collaborators". This came in reaction to Avnery earlier saying on Israeli radio station Kol Israel that the assassination of Israeli tourism minister Rehavam Zeevi was a Palestinian "targeted killing", like the Israeli military's "targeted killings" of Palestinian political leaders. According to Gush Shalom, "the radio did not quote [Avnery's] next words: 'I am against all assassinations, both by Israelis and Palestinians.'"
