Opposition to the Iran deal has doubled since June, with the public divided nearly evenly between those supporting the agreement and those opposed, according to a new NBC News/Wall Street Journal poll.
The new survey, released Monday, found 35 percent in favor of the deal, 33 percent against it and 32 percent not knowing enough to have an opinion.
Those figures have shifted significantly since mid-June before the administration announced that a deal had been reached and Congress and the American people had a chance to consider its details.
In mid-June, the same survey found that 36 percent of the public supported the deal while 17 percent opposed it and 46 percent said they didn’t know enough to have an opinion.
Since the Obama administration announced the agreement, reached last month between Iran, the U.S. and six other world powers, the American public has largely split along ideological lines.
Democrats are backing the deal by a 58-8 percent margin, while Republicans oppose it, 60-15 percent, the poll found.
More self-described independent voters, meanwhile, oppose the deal then support it, 39-24 percent.
The NBC News/Wall Street Journal commissioned poll was conducted July 26-30 and has a margin of error of plus or minus 4.4 percentage points.
