California, which leads all the states in enrollment, had met 90 percent of its goal with 728,086 signed up.
Texas, which has the highest proportion of uninsured residents of any state, was subpar. It met 53 percent of its goal.
Blewett said the federal website appears to be outperforming portals run by the states. States where the feds are in charge met 80 percent of their enrollment targets, compared with 70 percent for states running their own insurance markets.
Surprisingly, the worst performers include four jurisdictions where Obama's law has strong support: Maryland, Massachusetts, Oregon and the District of Columbia. The three states on that list have all had problems with their enrollment websites.
"Maybe it's time for the feds to send some SWAT teams and resources and help turn the corner on technological glitches," said Blewett.
