The poll, conducted by Hart Research for the advocacy group Americans United for Change, shows some 67 percent of respondents said they would prefer to give the deal and further negotiations a chance, rather than having Congress pass new economic sanctions and 25 percent disagreed, Los Angeles Times reported on Tuesday.

According to the poll, a plurality of Americans supported the interim nuclear deal with Iran, 34 percent to 22 percent, and 41percent had no opinion on the complex agreement.

It found that after a sample group was read a description of the deal, 63 percent favored it and 24 percent were opposed. The remaining 13 percent were undecided.

The interim deal between Iran and the five permanent members of the United Nations Security Council – the United States, Britain, France, China and Russia – as well as Germany offers Iran limited temporary relief from some economic sanctions in return for freezing some elements of its nuclear program, while the two sides try to reach a long-term deal.

The Obama administration and its supporters are lobbying Congress not to adopt new sanctions while negotiations are underway, arguing that new unilateral measures would undermine the talks.

But a bipartisan group of senior senators is preparing to try to pass a sanctions bill before the Senate adjourns for its holiday break.

The survey polled 800 voters between Nov. 26 and Sunday. No polling was conducting on Thanksgiving or the day after.
