Romney also joined a chorus of criticism Obama has received as hundreds of thousands of Americans have been notified that their health insurance policies have been canceled. The cancellations appear to contradict the president's pledge that, despite the changes brought by his reforms, Americans would be able to keep their health insurance if they like it.
"He told people they could keep their insurance, and that was not the truth," Romney said.
Backers of the president's plan insist that those being forced to change their insurance had low-quality plans and that most would be able to get better coverage for the same amount or less.
Gov. Deval Patrick, Romney's successor, insisted that there were lessons to be gleaned from his state's experience.
"It took us two years to get our website right in Massachusetts," Patrick said on NBC. But now the state has near-universal insurance coverage and broad popular support for the program, he said.
The federal healthcare.gov website was down overnight Saturday and into Sunday, the latest in a continuing string of problems.
Dan Pfeiffer, a top White House adviser, said the system can be fixed by the end of November. "There's no question we have to get this done by the end of this month," he said on ABC's "This Week." Pfeiffer acknowledged that enrollment numbers to be released later this month "are not going to be what we want them to be."
"The website hasn't worked the way we want it to work. But we take responsibility for that, take responsibility for the errors, take responsibility for fixing it," he said. "And if we get the website working as expected we do by the end of this month, then I think we're going to be in a good place."
Cruz not on Romney's list of presidential contenders
Washington • Mitt Romney isn't including tea party favorite Ted Cruz among the Republicans' most electable potential presidential candidates in 2016.
Who does the 2012 GOP nominee put on his list of "very capable people"?
His ex-running mate, Wisconsin Rep. Paul Ryan. Florida Sen. Marco Rubio. Former Florida Gov. Jeb Bush.
But Romney says New Jersey Gov. Chris Christie "stands out as one of the very strongest lights."
Romney was asked on NBC's "Meet the Press" whether Cruz is a "potential light."
Romney said he's not going to disqualify anybody. But he made clear that he had given the names of those he thought were "the most effective in becoming elected."
Cruz led the GOP effort to shut down the government in an effort to dismantle Obama's health care law.
