President Obama must decide now how he wants to govern in the two years leading up to the 2012 presidential election.

In recent days, he has offered differing visions of how he might approach the country’s problems. At one point, he spoke of the need for “mid-course corrections.” At another, he expressed a desire to take ideas from both sides of the aisle. And before this month’s midterm elections, he said he believed that the next two years would involve “hand-to-hand combat” with Republicans, whom he also referred to as “enemies.”

It is clear that the president is still trying to reach a resolution in his own mind as to what he should do and how he should do it.

This is a critical moment for the country. From the faltering economy to the burdensome deficit to our foreign policy struggles, America is suffering a widespread sense of crisis and anxiety about the future. Under these circumstances, Obama has the opportunity to seize the high ground and the imagination of the nation once again, and to galvanize the public for the hard decisions that must be made. The only way he can do so, though, is by putting national interests ahead of personal or political ones.

To that end, we believe Obama should announce immediately that he will not be a candidate for reelection in 2012.

If the president goes down the reelection road, we are guaranteed two years of political gridlock at a time when we can ill afford it. But by explicitly saying he will be a one-term president, Obama can deliver on his central campaign promise of 2008, draining the poison from our culture of polarization and ending the resentment and division that have eroded our national identity and common purpose.

We do not come to this conclusion lightly. But it is clear, we believe, that the president has largely lost the consent of the governed. The midterm elections were effectively a referendum on the Obama presidency. And even if it was not an endorsement of a Republican vision for America, the drubbing the Democrats took was certainly a vote of no confidence in Obama and his party. The president has almost no credibility left with Republicans and little with independents.
