Despite his earlier declarations to the contrary, Lieberman opposes electing half the Knesset in regional elections.
Direct elections stand to benefit Avodah and Kadima, who have many popular personalities on board; their candidates can easily win local (majoritarian) elections. Lieberman has no candidates who would unquestionably win local elections; his support base is dispersed throughout the country. Thus, Yisrael Beitenu supports country-wide (proportional) elections.
Political theory views regional elections as expedient, but national ones as more just as they better reflect the will of all citizens.
