This week, we're focusing on the Israeli elections set for September 17. Voters will be casting ballots for the second time in one year, after the last vote in April failed to produce a clear winner. This month's poll pits the party of PM Benjamin Netanyahu - who is mired in corruption scandals - against that of Benny Gantz, who appeared out of nowhere just months before the April vote. We're joined by Gideon Rahat, a political science professor at the Hebrew University of Jerusalem.
