Washington (CNN) – A majority of Americans who watched President Barack Obama's prime time address to the nation on Tuesday said they favor the approach to Syria that the president spelled out in his speech, according to an instant poll.
But an exclusive CNN/ORC International survey of speech-watchers conducted immediately after the conclusion of Obama's address also indicates that those who tuned into the address were split on whether the president made the case for military action against Syria.
Sixty percent of those questioned said it was not in the national interests of the U.S. to be involved in the bloody two year old Syrian civil war, and more than half said the speech did not change their confidence in the president's leadership on military and international issues.
According to the poll, 61% said they support the president's position on Syria, with 37% saying they oppose his response to the Syrian government's alleged use of chemical weapons against its own citizens.
The president said in his speech that he's asked congressional leaders "to postpone a vote to authorize the use of force" against Syrian President Bashar al-Assad's military while diplomatic efforts to address the crisis continue. "It's too early to tell whether this offer will succeed, and any agreement must verify that the Assad regime keeps its commitments," Obama said. "But this initiative has the potential to remove the threat of chemical weapons without the use of force."
The poll indicates that nearly two-thirds of those who watched the speech think that the situation in Syria is likely to be resolved through diplomatic efforts, with 35% disagreeing.
But Obama said that he's ordered the U.S. military "to maintain their current posture to keep the pressure on Assad, and to be in a position to respond if diplomacy fails."
According to the poll, those who watched the president were divided on whether Obama made a convincing case in his speech for U.S. military action in Syria, with 47% saying he did and 50% saying he didn't.
The survey indicates that the speech didn't move the needle very much on whether U.S. air strikes against Syria would achieve significant goals for the U.S. Thirty percent of speech-watchers questioned before the address said yes. That number edged up to 36% following the address. And 39% said it was in the national interests of the U.S. to be involved in the conflict in Syria, edging up from 30% before the speech. Sixty percent said it was not in the national interests to get involved, down just five points from before the speech.
Fifty-two percent said following the speech that they were more confident of the president's leadership on military and international issues, with 16% saying they were less confident. But 52% said the speech did not change their opinion.
The sample of speech-watchers in the poll was 37% Democrats, 20% Republicans, and 43% independents. CNN's best estimate of the number of Democrats in the voting-age population as a whole indicates that the sample is about seven percentage points more Democratic than the general public.
The CNN poll was conducted immediately after the speech over the phone by ORC International with 361 adult Americans who watched the address. The survey's sampling error is plus or minus five percentage points.
