WASHINGTON (AP) - The Obama administration said Sunday that the worst of the online glitches, crashes and delays may be over for the problem-plagued government health care website, a key component of President Barack Obama's signature domestic policy initiative.
The stakes are high for Obama who has seen his approval ratings drop sharply since the rocky Oct. 1 rollout of the HealthCare.gov website, threatening his ability to advance his second-term agenda. The website's shaky launch has left Obama's fellow Democrats nervous ahead of next year's elections when control of Congress will be at stake.
The Department of Health and Human Services said Sunday that the website is working more smoothly. But that doesn't mean HealthCare.gov is ready for a clean bill of health.
Officials acknowledged more work remains on the website that included hundreds of software bugs, inadequate equipment and inefficient management for its national debut two months ago. Federal workers and private contractors have undertaken an intense reworking of the system, but the White House's chief troubleshooter cautioned some users could still encounter trouble.
"The bottom line - HealthCare.gov on Dec. 1 is night and day from where it was on Oct. 1," Jeff Zients told reporters.
More than 50,000 people can log on to the website at one time and more than 800,000 people will be able to shop for insurance coverage each day, the government estimated in a report released Sunday. If true, it's a dramatic improvement from the system's first weeks, when frustrated buyers watched their computer screen freeze, the website crash and error messages multiply.
HealthCare.gov, which services 36 states, signed up just 27,000 people for health insurance coverage in October, while the 14 states that run their own websites enrolled 79,000. The total of roughly 106,000 was far off the administration's estimate that nearly 500,000 people would enroll within the first month of the six-month enrollment period.
The new figures for the website's capacity - which could not be independently verified - suggest millions of Americans could turn to their computers to shop for and buy policies from private insurers by the Dec. 23 deadline so their coverage can kick in on the first of the year.
"There's not really any way to verify from the outside that the vast majority of people who want to enroll can now do so, but we'll find out at least anecdotally over the coming days if the system can handle the traffic and provide a smooth experience for people trying to sign up," said Larry Levitt, a senior adviser at the Kaiser Family Foundation.
But, he added, HealthCare.gov is clearly working better than when it first went online. Its challenge now is to convince users who were frustrated during their first visit to give it another chance.
Politically, a fixed website could also offer a fresh start for Obama and his fellow Democrats after a wave of bad publicity surrounding the president's chief domestic achievement.
"This website is technology. It's going to get better. It's already better today," said Democratic Rep. Keith Ellison, who is a co-chairman of the liberal Congressional Progressive Caucus. "And we're only going to be working out more kinks as we go forward."
Amid all the problems with HealthCare.gov, Obama set a deadline for Saturday for several significant problems to be resolved. The administration organized a conference call with reporters Sunday morning to give a status report and boast that 400 technical problems had been resolved but declined to say how many items remain on the to-do list.
Even with the repairs in place, the site still won't be able to do everything the administration wants, and companion sites for small businesses and Spanish speakers have been delayed. Questions remain about the stability of the site and the quality of the data it delivers to insurers.
Obama promised a few weeks ago that HealthCare.gov "will work much better on Nov. 30, Dec. 1, than it worked certainly on Oct. 1." But, in trying to lower expectations, he said he could not guarantee that "100 percent of the people 100 percent of the time going on this website will have a perfectly seamless, smooth experience."
Obama rightly predicted errors would remain. The department reported the website was up and running 95 percent of the time last week - meaning a 1-in-20 chance remains of encountering a broken website. The government also estimated that pages crashed at a rate less than once every 100 clicks.
"Yes, there are problems," said Rep. Chris Van Hollen, the top Democrat on the House Budget Committee. "There's no denying that. Let's work to fix them."
The nation's largest health insurer trade group said significant problems remain and could be a barrier for consumers signing up for coverage effective Jan. 1.
"HealthCare.gov and the overall enrollment process continue to improve, but there are significant issues that still need to be addressed," said Karen Ignagni, president and CEO of America's Health Insurance Plans.
Republicans, betting frustration about the health care law is their best bet to make gains in 2014's congressional and gubernatorial elections, continued their criticism of the system. Republicans need to gain six seats to take control of the Senate, while Democrats need to gain 17 seats to win back the majority in the House of Representatives.
"I don't know how you fix it, I'll be honest," said Republican Sen. Bob Corker. "I don't know how you fix a program that was put together in this manner with only one side of the aisle, and taking the shortcuts we're taking to put it in place."
Democrats, sensing their potential vulnerability, sought to blame Republicans for not offering ideas on how to improve the website.
"Yes, we have to fix it. We should be working together to fix it," said Van Hollen, a former chairman of the committee tasked to elect more Democrats to the U.S. House.
The first big test of the repaired website probably won't come for a few more weeks, when an enrollment surge is expected as consumers rush to meet a Dec. 23 deadline so their coverage can kick in on the first of the year.
Avoiding a break in coverage is particularly important for millions of people whose current individual policies were canceled because they don't meet the standards of the health care law, as well as for a group of about 100,000 in an expiring federal program for high-risk patients. The law requires most people who don't have health insurance to buy coverage or pay fines.
For the system to be successful, the administration needs large numbers of mostly younger, healthy people to buy coverage to help offset the cost of insuring older people who generally use more health care services. Federal subsidies are available to those who qualify to help lower the cost of insurance.
