President Barack Obama and the Democrats have a big challenge ahead of them at the Democratic National Convention this week.
They have to answer the challenge thrown down last week at the Republican National Convention, when Mitt Romney told voters to ask themselves whether they are better off than they were four years ago, and if not, what will the current administration do in the next four years to make things better?
Obama and Joe Biden are going to have to come up with some other answer than "Don't blame us, we inherited this mess from George W. Bush."
Whatever the Obama Adminstration inherited three and a half years ago is ancient history. He has had time to put his imprint on the country, and so far that hasn't been much.
The economy remains stagnant. The federal deficit has soared. Unemployment remains high. The president managed to ram through a hugely unpopular and complex health care reform law.
The president, far from being someone who builds coalitions and brings people together, has been just as partisan and polarizing as anyone in Washington.
So the question for the president, as he accepts his party's nomination, is this: What will you do differently in the next four years?
That should be one heck of a speech.
