Ex-army chief Gadi Eisenkot, who lost his son in Gaza, leads the race to oust Netanyahu in Tuesday's Israeli election
Benjamin Netanyahu faces a deadlocked election on 27 October, with Arab parties holding enough seats to hand the opposition a majority if it joins forces with them.
President Trump's own advisers reportedly believe a Benjamin Netanyahu defeat could make his Middle East agenda easier to advance. That is despite Trump endorsing the Likud leader only last Sunday. A polling average puts the anti-Netanyahu bloc on 53 seats to his 51, with neither side near the 61 needed. Tens of thousands of Israelis are flying home to vote him out.
Eisenkot's son Gal Meir Eisenkot, 25, died in combat in Gaza, and two nephews followed him.
'He's the devil he knows,' one Trump adviser said of Netanyahu.
Netanyahu, 77, is already Israel's longest-serving prime minister and wants up to four more years.
