It found that 56 percent oppose the program compared with 63 percent in September.

A higher proportion of the uninsured also said they are interested in buying insurance on the exchanges, with 42 percent in October, saying they were likely to enroll compared with 37 percent in September.

“The launch of the exchanges, that’s the first real world event for a lot of people,” said Chris Jackson, an Ipsos pollster. “There’s been this sense that once people got familiar with it, public opinion would start to move in its direction.”

The online poll of nearly 12,000 people was conducted in October.
