Most Americans believe that a nuclear deal with Iran would not make a real difference in preventing that country’s production of a nuclear weapon, according to a new NBC/Wall Street Journal poll.

Seventy-one percent of Americans say that the nuclear negotiations, which are backed by the Obama administration and strongly opposed by most Republicans, will not make a real difference in affecting Iran’s potential production of a nuclear weapon. About a quarter of respondents – 24 percent – disagree.

Democrats are more optimistic about the deal, with about a third believing that it would be effective in preventing the production of an Iranian bomb, compared to just 11 percent of Republicans who say the same. But majorities of Americans from all political parties – 58 percent of Democrats, 72 percent of independents and 86 percent of Republicans – think that the deal would not make a major difference.

The new numbers come as all but seven GOP senators penned a letter to the Iranian government warning them that Congress could undo any deal negotiated by the Obama administration.
