According to Sharon supporters, on the first day after its founding, Kadima already had nearly 150 members, most of whom were defectors from Likud. Several Knesset members from Labor, Likud, and other parties immediately joined the new party, including cabinet ministers Ehud Olmert, Tzipi Livni, Meir Sheetrit, Gideon Ezra and Avraham Hirschson. Deputy ministers Ruhama Avraham, Majalli Wahabi, Eli Aflalo, Marina Solodkin, Ze'ev Boim and Yaakov Edri also joined the party, along with Likud MKs Roni Bar-On and Omri Sharon.
