A poll of American Jewish voters shows that they overwhelmingly support Barack Obama for president, just as they did four years ago, and that Israel and Iran rank low on their list of priority issues in the presidential election.

The results cast doubt on the claim that Mr. Obama has alienated a significant swath of Jewish voters because of his rocky relationship with Israel’s prime minister, Benjamin Netanyahu.

“We show no slippage in Jewish support for President Obama,” said Robert P. Jones, chief executive of the Public Religion Research Institute, an independent research group based in Washington D.C., which conducted the poll of 1,004 Jewish adults from Feb. 23 to March 5. The margin of error is plus or minus five percentage points.

Support for Mr. Obama is still higher among Jews than among the general electorate, with 62 percent of Jewish voters saying they would like to see him elected, and 30 percent saying they preferred the Republican candidate. (That is almost identical to a Gallup poll of American Jewish registered voters taken in June 2008.)

Of the 30 percent of those polled who said they preferred a Republican candidate, 58 percent said they supported Mitt Romney, 15 percent supported Rick Santorum, 13 percent supported Newt Gingrich and 12 percent supported Ron Paul.

Asked to rank which issues were most important to their vote for president, about half of American Jews cited the economy, and 15 percent cited the growing gap between the rich and the poor. Concern about Israel or Iran ranked very low, even when respondents were asked for the second most important issue that would determine their vote for president.

On relations between the United States and Israel, 54 percent of those polled said relations were about the same as in the past, while 37 percent said they were worse, and only 7 percent said they were better. Only 20 percent said they liked the way that Mr. Obama had handled the Arab-Israeli conflict and that they agreed with his policies, while 15 percent said they agreed with the president’s policies, but didn’t like the way he was carrying them out. Twenty-eight percent said they disagreed with his policies, and 36 percent said they were not sure

“We see some tensions here,” Mr. Jones said, “but ultimately when it comes down to who they’re going to choose as president, it’s not what’s driving the vote.”
