A majority of Americans support the Iran nuclear deal and think the United States should not withdraw, according to polls conducted by CNN, Morning Consult and Politico. But a CBS News poll found that many Americans don't know enough about the 2015 accord to say what the United States should do. Most Americans have heard only "a little" about the agreement, according to a Pew Research Center survey. Around 26 percent have heard nothing at all. President Trump is due to make a decision on the accord by May 12, when sanctions waivers are due for renewal. He has been extremely critical of the deal and threatened to withdraw multiple times, despite repeated confirmation of Iran's compliance by the International Atomic Energy Agency. The following are excerpted results from the surveys. 

 

Morning Consult/Politico Poll

Public support for the Iran nuclear deal is at a record high, according to a new poll by Morning Consult and Politico. The survey, which was conducted online between April 26 and May 1 among 1,991 registered voters, showed 56 percent supported the 2015 accord, matching a previous high from April 2017. Net public support was at an all-time high of 30 percent. Just 26 percent opposed the deal, the lowest opposition since the survey began in August 2015. Democrats and independents were in favor of the nuclear agreement overall, but Republicans were split - 46 percent supported the deal and 42 percent opposed it.

 

How much confidence do you have in President Trump to handle threats posed by Iran? 

 

As you may know, the United States and other countries made a deal in 2015 to lift economic sanctions against Iran in exchange for Iran agreeing not to manufacture nuclear weapons. This agreement is sometimes referred to as the Iran nuclear deal. Knowing this, do you support or oppose this agreement?

 

 

CNN Survey

Almost two-thirds of Americans (63 percent) think the United States should not withdraw from the 2015 Iran nuclear deal, as opposed to 29 percent that support the decision to withdraw, according to a CNN poll conducted by SSRS. Despite the majority backing the accord, 62 percent think Iran has violated the terms of the agreement. The survey received 1,015 respondents and was conducted from May 2 to May 5, 2018. 

 

Do you approve or disapprove of the way Donald Trump is handling the U.S. relationship with Iran?

 

Would you say that Iran represents a very serious threat to the United States, a moderately serious threat, just a slight threat, or no threat at all?

 

As you may know, the United States and five other countries entered an agreement with Iran aimed at preventing Iran from developing nuclear weapons. Do you think the U.S. should or should not withdraw from that agreement? 

 

Regardless of what you think about whether the U.S. should withdraw from that agreement, do you think that Iran has or has not violated the terms of the agreement? 

 

 

CBS News Poll

A majority of Americans (57 percent) say they don't know enough to give an opinion about what the United States should do in regards to the Iran nuclear deal, according to a CBS News poll. The remaining survey were split on the decision to withdraw or not - 21 percent for withdrawing from the deal and 21 percent against. The poll found that Republicans were more likely to support leaving the 2015 accord, but almost half didn't know enough to say. The CBS News poll received 1,101 responses and was conducted by telephone between May 3 and May 6, 2018. 

Do you think the United States should remain in the 2015 Iran nuclear deal, or do you think the United States should leave the 2015 Iran nuclear deal, or don't you know enough about it to say?
