The March 23rd vote will be Israel's 4th Knesset election in two years – and many of the names on the rosters are relatively new to the Knesset. According to an Israel Democracy Institute review, only 25 of the 120 MKs elected in the 2009 elections are expected to be elected in this current round as well. Why is there such turnover? Do politics need new faces, or is the work of the legislature harmed by lack of specialization and experience? KAN reporter Naomi Segal put the  questions to Prof. Ofer Kenig, a researcher at the Israel Democracy Institute who conducted the analysis.
