Good news for Obama, though there's never a guarantee. From Alan Abramowitz:
The 2012 presidential election is still more than 20 months away. While the early maneuvering for the Republican presidential nomination is already underway, the identity of President Obama’s GOP challenger won’t be known for more than a year. Economic trends will have a major impact on the President’s reelection chances and unpredictable events, such as the recent political turmoil in Egypt, could also affect the public’s evaluation of the President’s performance.
But even without knowing what condition the economy will be in, whether a major international crisis will erupt, or who will win the Republican nomination, one crucial determinant of the outcome of the 2012 presidential election is already known. Barack Obama will be seeking reelection as a first term incumbent and first term incumbents rarely lose.
