Eugene Robinson: “There remains the technical impediment that the president is constitutionally barred from a third term. But the longer the campaign goes on, the higher Obama’s approval rating rises. This should be bad for Donald Trump and good for the eventual Democratic nominee, almost certainly Hillary Clinton. But it is even better for Obama’s legacy.”

“According to Gallup, which has been charting the nation’s assessment of its presidents longer than anyone else, Obama’s approval stands at 52 percent, compared with 44 percent disapproval. That may not look impressive but it is actually quite good for a president nearing the end of his second term; Ronald Reagan, by comparison, had 49 percent approval at this point in his tenure.”

“We tend to appreciate presidents more after they leave office. The inevitable reassessment of the Obama years seems to be starting early — perhaps in apprehension of the years to come. Even Obama’s harshest critics have to admit he was a steady hand in the White House. Reflection upon this fact can only increase Clinton’s chances against a man who prides himself on being combative, capricious and cocksure.”
