Most Americans don't know what U.S. should do on Iran deal – CBS News poll

Fifty-seven percent of Americans say they don't know enough to say what the U.S. should do about the Iran nuclear deal which was brokered in 2015. Those with an opinion divide evenly on whether the U.S. should remain in the deal (21 percent) or leave the deal (21 percent).

By a margin of more than 3 to 1, Republicans are more likely to advocate leaving the Iran deal than remain in it, although nearly half don't know enough to say. Most Democrats (more than 6 in 10) don't have an opinion either way, but those who do hold a view are more inclined to think the U.S. should stay in the deal.


The president said Monday he will announce his decision on the deal Tuesday afternoon.

This poll was conducted by telephone May 3-6, 2018 among a random sample of 1,101 adults nationwide.  Data collection was conducted on behalf of CBS News by SSRS of Glen Mills, Pa. Phone numbers were dialed from samples of both standard land-line and cellphones.

The poll employed a random digit dial methodology. For the landline sample, a respondent was randomly selected from all adults in the household. For the cellphone sample, interviews were conducted with the person who answered the phone.

Interviews were conducted in English and Spanish using live interviewers. The data have been weighted to reflect U.S. Census figures on demographic variables.

The error due to sampling for results based on the entire sample could be plus or minus three percentage points. The error for subgroups may be higher and is available by request. The margin of error includes the effects of standard weighting procedures which enlarge sampling error slightly.
