About two-thirds of American adults say the war with Iran was not worth it [1].
The finding underneath that one is the one worth sitting with: 37 percent of Republicans say the same.
The movement is inside the president's own party
Approval of his handling of Iran stands at 28 percent overall, down from 34 percent a month earlier [1].
Among Republicans it has fallen from 71 percent in June to roughly 61 percent - about ten points in four weeks [1].
That is a different shape from an ordinary partisan split. Opposition to this war is not being supplied almost entirely by one side; more than a third of the president's own coalition is in it.
When the fieldwork actually ran
The poll was conducted by the Associated Press and NORC at the University of Chicago between July 23 and July 27 [1].
That window closes before a great deal of what has happened since:
- the CENTCOM strike wave on the night of July 29
- the Senate coming within one vote of forcing a war-powers debate on July 30
- the unclaimed drone strike on shipping at Egypt's Damietta port
These numbers therefore describe opinion as it stood at the start of that week, not after it. Whatever the past three days did to public sentiment is not measured here, in either direction.
What this is useful for
Mostly as a check on a claim. Any assertion that the country is behind this war now has a dated survey to be measured against, and the assertion does not survive it.
