TEL AVIV, Israel (AP) — After falling out with Benjamin Netanyahu as a junior member of the Cabinet last year, Avi Gabbay is now a leading candidate to replace the scandal-plagued prime minister. Buoyed by a rags-to-riches personal story and a centrist worldview that appeals to Israel's traditional swing voters, the new leader of the opposition Labor Party has seen a big bump in the polls. But the 50-year-old former telecom executive has his sights set on more than just victory at the ballot box: He believes his business background and everyman persona could enable him to reach a peace agreement with the Palestinians — something that Netanyahu rarely even mentions anymore.
