John Cassidy thinks it's possible: "Carefully crafted to rally his Democratic base while also appealing to independent voters, it was the speech of a front-runner who thinks he can win if the current dynamic is maintained, and he may well be right."
And he picked up on the contrast with Romney, though he uses the politically smart and very civil, gentlemanly manners when he refers to "the opposition" in preference to naming names.
... When he attacked his opponent, he did it in a low-key fashion. If the Obama campaign believed that he was in trouble, he may well have raised Romney’s record at Bain Capital and his failure to release more tax returns, but here he was content to wield the stiletto rather than bludgeon, noting, “You might not be ready for diplomacy with Beijing if you can’t visit the Olympics without insulting our closest ally.” ... Cassidy, NewYorker
Stilettos are effective. And they don't leave a mess. Which is a lot more than we can say about the president's crude and ungentlemanly opposition.
