Public opinion of Obamacare has never been worse, even as the government-run health insurance exchanges are running dramatically better than they did when they opened last year.

Just 37 percent of Americans approve of the Affordable Care Act, 1 percentage point less the previous low seen last January, the Gallup public opinion research organization said Monday.

And 56 percent of people disapprove of the ACA, which is 1 point higher than the previous high, Gallup said.

The poll was released two days after open enrollment in ACA insurance plans resumed on the online government Obamacare exchanges.

"In the first two days of open enrollment we have seen 1 million visitors" to HealthCare.gov, the federally run Obamacare exchange, said Health and Human Services Secretary Sylvia Mathews Burwell.



"We have had 200,000 calls to customer care centers ... and 20,000 of those are to our Spanish-language lines," she said.

Burwell also said more than 100,000 people filled out applications on the first day for insurance coverage on HealthCare.gov, which serves residents of 37 states. She said she did not know how many people out of that had actually enrolled in coverage.

That is a significant difference from Obamacare's open-enrollment launch one year ago. At that time, a technological meltdown prevented all but a handful of people from creating accounts or applying for coverage, much less signing up for health plans on HealthCare.gov, and several other exchanges.

A year ago, the site was so hobbled by technical problems that only six people were able to complete the process on opening day.
