(CNN) - Senior Clinton advisers blasted Sen. Barack Obama’s campaign Monday after a major Obama supporter in Iowa compared Bill Clinton unfavorably to Joe McCarthy and referenced the blue dress at the heart of the impeachment scandal.
"When Joe McCarthy questioned others' patriotism, McCarthy (1) actually believed, at least aparently, the questions were genuine, and (2) he did so in order to build up, not tear down, his own party, the GOP,” wrote Gordon Fischer, a former chair of the Iowa Democratic Party, wrote on his blog. “Bill Clinton cannot possibly seriously believe Obama is not a patriot, and cannot possibly be said to be helping — instead he is hurting — his own party. B. Clinton should never be forgiven. Period. This is a stain on his legacy, much worse, much deeper, than the one on Monica's blue dress."
Fischer was referring to President Clinton’s comments over the weekend that a race between John McCain and Hillary Clinton would be a contest between two people who love their country, which some Obama supporters - including former Air Force Gen. Tony McPeak – have interpreted as an attack on Obama's patriotism.
Fischer later removed the post from his blog, replacing it with an apology. ”I sincerely apologize for a tasteless and gratituous comment I made here about President Clinton,” he wrote. “It was unnecessary and wrong. I have since deleted the comment, and again apologize for making it. It will not happen again. I hope my readers will accept my apology and we can move on to the very important issues facing our state and country. Thank you.” Fischer endorsed Obama last fall.
In a conference call with reporters Monday, Clinton aides said Fischer’s decision to attack the New York senator in “starkly personal terms” reflected “gutter tactics that (the Obama) campaign is now deploying.”
“It would appear to be that their high-minded rhetoric seems to be falling short,” said spokesman Phil Singer.
"This is now the Obama campaign’s primary message to the American people," said spokesman Howard Wolfson. "Not to build him up, but to tear Senator Clinton down."
He also dismissed Fischer’s apology. "That's all well and good… In my opinion the remarks of Gordon Fisher are very much in keeping with the campaign Senator Obama is running. So I don't know why he would apologize."
They also distanced themselves from remarks this weekend made by Clinton supporter James Carville, who seemed to compare Bill Richardson’s decision to endorse Barack Obama to Judas’ betrayal of Jesus.
"I'm not an expert on the topic to give a good answer," said Wolfson, who added that he would not have used those words and that in his view Richardson had served his country honorably.
UPDATE: Obama campaign spokesman Bill Burton responded: "As Senator Obama has said repeatedly, comments like this have no place in our political dialogue and he strongly rejects them," said Burton.
In an e-mail to CNN's Richard Greene, Gordon Fischer said of his decision to remove the post: "I took it down becuase it was wrong. And stupid."
UPDATE at 3:29 p.m.: “I was quoted accurately and in context, and I was glad to give the quote and I was glad I gave it,” Carville told the New York Times, after Wolfson told reporters that he would have offered his apologies if he had made the remark. “I’m not apologizing, I’m not resigning, I’m not doing anything.”
