Pre-election jitters and shakes in the Russian sector. The two parties that were established for new immigrants, and chiefly for Russians - Yisrael B'Aliyah of Natan Sharansky and Yisrael Beiteinu of Avigdor Lieberman - are at odds as to whether they will merge. Lieberman published a letter in the Russian-language paper Vesti today, claiming that Sharansky has no intention of following through on his declaration that he will unite with Yisrael Beiteinu. Lieberman again called on Yisrael B'Aliyah to either join his party or to form a united Knesset faction with it.
