President Trump has taken to social media and the airwaves to promote the agreement last week between the United States and Iran to end the war.
Americans are unconvinced, but there is a political divide, according to a new Quinnipiac University poll taken after the deal was signed.
Nearly 60 percent of voters say they lack confidence in the deal’s effectiveness. That pessimism is driven by Democrats, with 90 percent saying they do not think the deal will be effective. A healthy majority of independent voters were also pessimistic.
A majority of the president’s base — 76 percent — felt confident in the pact. But there are signs of potential cracks. Only one-quarter of Republicans say they are “very confident” and about 20 percent say they are “not so confident” or “not confident at all.”
Most voters — including a majority of Republicans — say it is likely that Iran will develop nuclear weapons.
Overall, 60 percent of voters said they thought “the military action against Iran” was not worth it, including 17 percent of Republicans.
And 45 percent of voters largely feel that it put the United States in a weaker position in the world.
Here, again, partisanship dictates how people are reacting to the war. Most Republicans think it has put the United States in a stronger position, while most Democrats think the United States is now in a weaker position.
The Times will occasionally feature polling that illustrates how Americans are feeling about the issues of the day. The numbers come from high-quality polls with a record for accuracy and rigorous methods.
