The American public is divided on the Iran nuclear deal, with 35 percent supporting it and 33 percent against it, according to results from a new NBC News/Wall Street Journal poll.

Another 32 percent say they don’t know enough to have an opinion.

Opposition to the deal has doubled since June – when 36 percent said they supported the deal and 17 percent opposed it.

Current attitudes about the agreement – reached between Iran and six world powers (including the United States) in an attempt to prevent Iran from producing a nuclear weapon – are largely split among partisan lines.

Democrats support the deal by a 58 percent-to-8 percent margin, while Republicans oppose it, 60 percent to 15 percent.

However, more self-described independents oppose the deal (39 percent) than back it (24 percent).

The poll was conducted July 26-30, and this question has a margin of error of plus-minus 4.4 percentage points.
