They aren't telling you the truth.
In the Senate, J-Street's candidates did particularly poorly.
A trusted source who tallies these sorts of things tells me that:
- Of the 23 senators up for reelection who opposed the Iran deal, 21 of them (91%) were reelected.
- J-Street only won 4 of 14 competitive and open seat senate races (29%).
- J-Street PAC spent tens of thousands of dollars on ads to support former Senator Russ Feingold, who was way ahead in the polls before J-Street got involved and made the Iran deal an issue. he lost to Republican Ron Johnson, who became the first Republican Senator to win reelection in Wisconsin in a presidential year since 1956.
Even in the House, J-Street is looked upon as toxic.
- Among the 55 newly elected House members (28R, 27D), only 5 (9%) accepted an endorsement from J-Street.
- Out of 31 competitive congressional races that J-Street got involved in, its candidates won only 7.
I also looked at J-Street's poll of Jewish voters that make it look as if they overwhelmingly support the Iran deal. The questions they asked were the worst sort of leading questions.
For example:
As you may know, the United States reached an agreement last year with Britain, Germany, France, China, Russia, and Iran that places significant limits on Iran's nuclear program to prevent Iran from developing a nuclear weapon in exchange for lifting economic sanctions on Iran. Details of the agreement include: putting international nuclear experts on the ground to inspect Iran's nuclear facilities, and capping the level at which Iran can enrich uranium to far below what is necessary to make a nuclear weapon. In exchange, Iran receives phased sanctions relief, including the unfreezing of up to $150 billion in Iranian assets as it complies with the terms of the agreement. Do you support or oppose this agreement?The question doesn't say anything negative about the deal, so naturally the people surveyed said that they were somewhat supportive of the deal.
If the question would have added a simple "...and after 15 years, Iran will be free to pursue nuclear weapons without any significant obstacles" the numbers of people who would have said they supported it would have gone way down. If the question would have mentioned Iran's threats to destroy Israel, the results would have been much different. But -Street dishonestly frames the question to lead people to the answer they want to trumpet.
In short - don't trust a word J-Street says. They are trying to gaslight you.
