As an example, see the conclusion to this story.
Obama, who was returning from meeting with Congressional leaders, may have been distracted by Republicans' icy reception to his $825 billion stimulus package, which is poised to pass on Wednesday even without a groundswell of Republican support.
You see? It's not his fault! It's opposition to the stimulus package laundry list of liberal spending projects that had him flustered. The story, which managed to squeeze two paragraphs about a similar episode* involving President Bush in the ellipsis above, simply must find a villain for any error by the "kind of really perfect" Mr. Obama. And these days all villains are Republicans. All.
*Actually, the stories aren't all that similar, as President Obama has been in the White House for 8 days whereas Mr. Bush's episode occurred in Beijing while attending a conference, and he had no ongoing familiarity with the location. Mr. Bush's gaffe proved him an idiot, as legend has it. What does his own say about Mr. Obama?
