Sen. Barack Obama at an event to honor the 60th anniversary of Israel’s independence in Washington, D.C.

"The fate of the world for the next four years... it's all going to boil down to a few old Jews in Century Village"… that's the assessment of the 2008 election campaign by Rabbi Ruvi New, according to the New York Times.

While the line is the kind that will get a laugh, the point he's making is very serious: Barack Obama could have a problem with some Jewish voters, especially in Florida.

Obama was in Boca Raton today speaking in a synagogue about foreign policy and his approach to Israel. Florida is critical, and Jews make up almost 4% of voters there. Many of them are elderly, and that's the group that has concerns about Obama.

He has received a lot of support from younger Jews – winning 45% of the Jewish vote in the primaries – if you don't include Florida and Michigan. But the latest Florida poll suggests Obama would lose to John McCain, while Hillary Clinton would win.

Obama didn't campaign in Florida and voters didn't get a chance to know him.
