The worst former President in US history, fresh from his last round of publicity for supporting Hamas, is sounding crazier and crazier: Former President Carter blasts Bush.

“I think as far as the adverse impact on the nation around the world, this administration has been the worst in history,” Carter told the Arkansas Democrat-Gazette in a story that appeared in the newspaper’s Saturday editions. “The overt reversal of America’s basic values as expressed by previous administrations, including those of George H.W. Bush and Ronald Reagan and Richard Nixon and others, has been the most disturbing to me.” …

Douglas Brinkley, a Tulane University presidential historian and Carter biographer, described Carter’s comments as unprecedented.

“This is the most forceful denunciation President Carter has ever made about an American president,” Brinkley said. “When you call somebody the worst president, that’s volatile. Those are fighting words.”

Has Mr. Brinkley been paying attention to Carter lately? These latest rants are nothing unusual for the man who invited Michael Moore to sit in the presidential box at the 2004 Democrat Convention, and wrote a book in which he endorsed Palestinian terror attacks against Israel. Carter is a disgrace, and has been for years.

Carter also unloaded on Tony Blair in a BBC interview, with the same talking points we hear continually from radical leftists and Islamists. And The Guardian, where they have both.

Carter also lashed out Saturday at British prime minister Tony Blair. Asked how he would judge Blair’s support of Bush, the former president said: “Abominable. Loyal. Blind. Apparently subservient.”

“And I think the almost undeviating support by Great Britain for the ill-advised policies of President Bush in Iraq have been a major tragedy for the world,” Carter told British Broadcasting Corp. radio.
