Palin attacks Romney's record on his announcement day

Boston (CNN) – Less than an hour before Mitt Romney was to announce his second bid for the White House in New Hampshire, Sarah Palin appeared in Romney’s hometown and set about picking apart the health care plan he supported as governor of Massachusetts, suggesting it may be a fatal flaw for his candidacy.

Surrounded by reporters for several minutes while visiting the Bunker Hill monument along Boston’s Freedom Trail, Palin delivered her unvarnished opinions of the Romney heath care plan, which mandated that Massachusetts residents purchase health insurance or else face penalties.

“In my opinion, any mandate coming from government is not a good thing, obviously and I am not the only to say so, but obviously there will be more explanation coming from Gov. Romney for his support of government mandates,” said Palin, on day five of her “One Nation” bus tour of historic sites on the East Coast.

Romney has faced almost unceasing criticism from conservatives within his party for the similarities between his legislation and the national health care reform passed by President Obama.

He has wrapped himself in the Constitution to defend himself, insisting that states, not the federal government, should have the right to develop their own laws and regulations.

Palin was not buying it.
