The ABC/Post question copied by J Street ran as follows: “The US and other countries have announced a deal to lift economic sanctions against Iran in exchange for Iran agreeing not to produce nuclear weapons. International inspectors would monitor Iran’s facilities, and if Iran was caught breaking the agreement economic sanctions would be imposed again. Do you support or oppose this agreement?”

When Pew asked the question without embellishment, the result was 48-38 against. When CNN asked it without embellishment, the result was 52-42 against. When the Israel Project asked it of Jews alone without embellishment, it was 45-40 against. The ABC/Post poll is an outlier, and so is the J Street poll.

Liberal Jews who want to support the deal — like Reps. Sander Levin and John Yarmuth, and Sen. Dianne Feinstein — will surely use these bad data points to shore up their case and comfort themselves. They’d better be wary. The hidden danger for them can be found in the Israel Project poll, and it’s this: The more people know, the more they are inclined to oppose it.

And they’re only going to learn more and more about it as the weeks pass.
