Criticize George W. Bush’s performance as president all you want: He earned plenty of it. But his performance as an ex-president can be summed in one word – class.

He has yet to utter a word of criticism or critique about his successor’s choppy performance in the Oval Office – even though Barack Obama has lamely tried to blame Bush for everything but the failure of Charlie Sheen’s marriage and Lindsay Lohan’s drug problems. Yet even in his just-released memoir of his White House years, “Decision Points,” Bush says not a single harsh word about Obama. And as most Americans know, there is plenty that could be said.

Bush is also doing a good job of showing up one of his own predecessors as president, Jimmy Carter, who, self-centered as ever – and in sharp contrast with tradition - spent the Bush years loudly complaining about him and trying to undercut his foreign policy. There’s a good one-word description for Carter that rhymes with “class,” and we all know what it is.

Will Obama’s rebuke by the voters in the midterm elections finally prompt him to “man up” and take responsibility for the shape the country is in? Or will he continue pointing fingers? Here’s one thing you can say for sure: He can’t blame his party’s drubbing in the midterms on George W. Bush. For that, he need only look in the mirror.
