Clinton campaign manager Patti Solis Doyle has written a letter to her counterpart at the Obama campaign, asking the Illinois Senator to stop running what she calls a “false ad” in NH that claims his health care plan would cover everyone.

Solis Doyle writes, “Your advertisement not only contradicts the judgment of health care experts, but public statements by your campaign and your candidate,” adding, “Senator Obama has pledged to put “honesty first” in this campaign. In that spirit I respectfully request that you stop running this ad which is misleading voters in New Hampshire. “

Clinton’s camp often cites experts who say Obama’s plan would leave out 15 million people out of the 47 million who are currently uninsured, and notes that even Obama himself has called the plan “virtually universal.” Solis Doyle says “It’s not enough for Senator Obama to say he covers everyone, especially when that is inaccurate. The American people need a President who will take the action necessary and fight for health care for every single man woman and child.”

Watch the ad for yourself here:

The Obama campaign says Hillary is playing politics, pointing out that the ad in question is old news. “The Clinton campaign didn’t say a word when this ad was released a month ago,” Obama’s New Hampshire press secretary tells Fox News’ Obama producer Bonney Kapp. “The only thing that’s changed since then is the poll numbers.”

“The truth is, Barack Obama’s universal plan will provide coverage to every single American who can’t afford it and do more to cut the cost of health care than any other plan in this race. Rather than spending their time attacking Barack Obama, the Clinton campaign should explain how exactly they plan to force every American to buy health insurance even if they can’t afford it.”

Clinton’s policy director took steps to address that question today, saying Hillary’s plan aggressively cuts costs, and would cap the percentage of income every American would pay in health care premiums — something no other Democrat would do. She also said she’d use “default enrollment” to sign up every uninsured American for health care, getting them into one of many coverage options when they come into contact with the health care system, go to school, or get a job. But Clinton still hasn’t said how she’ll penalize people who still don’t enroll, saying only that she’ll work with Congress on the issue.

UPDATE: Obama’s national spokesman just put out a statement that’s word-for-word the same as the New Hampshire statement, but does NOT call the plan “universal.” instead, Bill Burton writes Obama “would offer health coverage to every single American,” rather than saying his universal plan will provide coverage to every single American.”
