America’s Jews account for a mere 2% of the U.S. population. But they have voted the Democratic ticket by margins averaging 78% over the past four election cycles, and their votes are potentially decisive in swing states like Florida and Pennsylvania. They also contribute an estimated half of all donations given to national Democratic candidates.
So whatever his actual convictions, it is a matter of ordinary political prudence that Barack Obama “get right with the Jews.” Since Jews tend to be about as liberal as the Illinois senator on most domestic issues, what this really means is that he get right with Israel.

Senator Barack Obama’s credibility gap resulting from his policies and disturbing pattern of association with anti-Semitic, anti-Israel, and anti-American friends and advisers is raising alarm throughout the Jewish community. The Democratic Party risks losing electoral and financial support from the Jewish community should Senator Barack Obama be the Party’s presidential nominee. Rank and file Democrats are telling pollsters that they will vote for Senator John McCain if Barack Obama is the Democrat’s choice, and major Jewish donors have already withheld support to the Democratic National Committee and other party efforts.
