The Obama administration fired another volley at GOP presidential candidate Mitt Romney’s attempt to distance himself from a Massachusetts health care law he signed in 2007.

“Governor Romney seems to running away from the law,” White House Press Secretary Jay Carney said, adding there are “lots of similarities” between the state law and the federal health care overhaul law adopted last year.

The 2007 law established Massachusetts as the first state in the nation to guarantee health insurance coverage for all its residents. Like the federal health care law, it requires people to purchase health insurance. Many conservatives oppose that idea.

Carney’s remarks came just ahead of a speech on health care reform that Romney gave at the University of Michigan.

The White House criticism was not surprising. Carney’s predecessor, Robert Gibbs, senior adviser David Axelrod and the president himself have made similar comments.

But they could complicate Romney’s efforts to explain his stance on the 2007 law during his campaign for the Republican presidential nomination.
