Poll Tracker

While slightly more than half of Americans said they currently oppose President Obama's health care overhaul proposal, almost the same number agree that some kind of overhaul is needed, according to a CNN/Opinion Research poll conducted Aug. 28-31.

The telephone survey of 1,010 adults found that 51 percent of those polled said they oppose Obama's plan and 45 percent said they favor it.

To the question, "Do you think the country's health care system needs a great deal of reform, only some reform, or no reform at all?" 45 percent said, a "great deal," 46 percent said, "only some," and 7 percent favored no changes to the current system.

Obama has scheduled a Sept. 9 address to a joint session of Congress and renew his call to pass legislation retooling the health insurance market this year. He is likely to more thoroughly detail his expectations for an overhaul, including what he deems an acceptable fallback to a public insurance plan that would compete against private insurers.
