RICHARD COHEN: “The presidency has changed Barack Obama. His hair has gone gray, which is to be expected, and he looks older, which is also to be expected, but his eloquence has been replaced by petulance and he has lost the power to persuade, which is something of a surprise. You can speculate that if the Obama of today and not Winston Churchill had led Britain in World War II, the Old Vic theater would now be doing ‘Hamlet’ in German.”

To be fair, some of us suspected that in 2008, while others admired his pants-crease.
