Footnotes
1. The Alternative for Yisrael split off from the Constitutional Liberal Party on November 7, 2019, at the end of the 48th term of Knesset and about two months from the 2020 general elections. 10 sitting Con-Lib MKs defected to the new party.
2. Torah Achdus neither sat in the opposition nor had a supply and confidence agreement with the ruling Conservatives.
3. The smaller Green Party and Yisraeli Labor Party merged together on February 8th, 2012, three weeks after the 2012 elections, combining their 4 seats (3 Greens, 1 Labor Party).
4. The Action Yisrael party was formed on May 24th, 2009, in advance of the 2010 elections.
5. The YCA was found to have illegal ties to anti-Yisrael terrorist groups the Christian Defense League and the Free Yarden Valley Catholic Front in the aftermath of the 2011 Yericho riots. Its MKs were arrested by the YeMep and the party banned under the Domestic Subversive Organizations Act before the 2012 elections.
6. None of the vacancies resulted in a change of partisan affiliation. All the seats were filled by persons of the same party.
7. Vice-President Oren Waltenstein would often be required to stay on premises for Knesset votes to cast the deciding vote due to the evenly-split Knesset between HRM Government led by the Con-Lib-Green-Labor-YCA-Indep. coalition (71) and HRM Opposition of the Conservatives and their allies the Torah Achdus party (71).
8. The Northern League, although in existence since 1974, had no won any seats since the 1980s. The party had a leadership election in February 14th, 2006, and elected David Touro as party chairman. Touro rebranded the party as "far right lite" and moderated the more extreme stances of the party as well as recruited credible right-wing activists and buildt needed campaign infrastructure in the Yarden River Valley to field successful candidates for the next election cycle.
9. The right-wing National Union merged with the Royalist Conservatives several months before the 2006 elections.
10. Avigdor Korvo, an former Con-Lib MK from Ashkelon who had defected to the Conservatives during the Whirlwind Knesset of 2002, switched back several days after the election from Conservative to Con-Lib and was given a prominent role on the Knesset Appropriations Committee.
11. In March 2002, the Hillel corruption allegations emerged. Over the next couple of months, more accusations and evidence surfaced, which led to calls for Hillel to resign. Defiant, Hillel initially refused, doubling down on his protestations of innocence. In April 2002, Con-Lib MK Avigdor Korvo defected to the Conservatives, citing Hillel's corruption and refusal to be held accountable. By May, a majority of the Con-Lib MKs agreed to bring a vote of no confidence and draft up articles of impeachment in cooperation with the Conservatives. In early June 2002, Hillel and Torah Achdus leader and MK Nechemia Valkenburger, who was accused of being in league with Hillel on various charges, resigned. Ariel Halevi, the registered Independent vice-president, became President. Fearing his centrist tendencies and lack of formal affiliation with the party, a group of left-wing Con-Lib MKs approached Halevi and demanded he become a Con-Lib to "comfortably" head the party. Halevi refused. Days after taking over, he fired scores of close Hillel confidantes and aides, replacing them with a mix of more moderate Con-Libs, non-partisans, and moderate Conservatives, much to the party establishment's shock. As detailed in the Whirlwind Knesset of 2002, a faction of Halevi-supporting Con-Libs broke with their Knesset leadership and formed the Independent Liberals. The leftist third parties refused to work with Halevi, so he stitched together a coalition of Independent Liberals and right-wing parties. That, too, fell apart after awhile. In 8 months, the Knesset had had three majorities rise and fall. In mid-2003, after Halevi announced he was not running for re-election, he and the Con-Lib establishment negotiated a deal towards the end of his term to make amends and the fractured Knesset Con-Libs reunited.
