Republican presidential nominee Mitt Romney at the Monday foreign policy debate, should play to the Jewish TV audience like he was the star of a Borscht Belt revue.

Romney has a tempting assortment of issues he can tap to frame President Barack Obama as a leader whose policies are perilous for Israel. He can use the Israeli-Palestinian conflict, Iran, Egypt and even Syria to make a case that Obama’s policies are wrong for the Jewish state.

Given the tenuous state of relations between Israel and the United States, it’s surprising that, according to a recent American Jewish Committee survey of Jewish opinion, 61 percent approve of Obama’s handling of U.S.-Israeli relations, while 39 percent disapprove. Those are numbers Romney needs to change Monday night.

He is not going to win the Jewish vote. Obama overpowered Senator John McCain in 2008 by 78 percent to 22 percent among Jews, and the most recent Gallup poll puts Obama ahead this year by 70 percent to 25 percent. But if Romney can narrow that 45 percent margin between him and Obama, he will increase his chance of becoming president.

While Jews are a small minority in the United States, they generally get to the polls in big numbers. Several swing states are home to relatively large populations of Jews, particularly Florida, Nevada and Pennsylvania, but also Virginia, Ohio and Colorado.
