In a country where media scrutiny is intrusively intense, he has suffered no scandals so far - personal, political or monetary (the Obamas' net earnings actually fell after he became president). Few US presidents can claim so many significant achievements; Mr Obama, the country's first African-American president, has done so in the face of unprecedentedly vicious and intense opposition. A Republican-controlled Congress is one element of that and it is a risk many presidents have run before; but Mr Obama has had the added pressure of parrying ingrained racism as exemplified by the "birther" controversy, which endured into his second term, and regular taunts about being Muslim from such unedifying personalities as Donald Trump. Yet the egregious Mr Trump, who hopes to secure the Republican nomination for the presidency, would have been one of many beneficiaries since Mr Obama took office.
Naturally, for a job as complex as the US president's, the performance is not flawless. For instance, though the unemployment rate may have fallen to 5.6 per cent from 7.8 per cent, when Mr Bush relinquished charge, long-term employment remains a challenge. More Americans live in poverty than they did in 2009 and Mr Obama's effort to spend his way out of recession has meant federal debt at $13 trillion has grown more during his term than all US presidents combined - it could be the cause of yet another Republican-orchestrated government shutdown in October. In foreign policy, his strategy against ISIS in West Asia has lacked conviction, nor has he been able to reassure Japan and Pacific Rim countries against China's belligerence. It is unclear how much he could have achieved here; Mr Obama, who set new standards of public probity with his crowd-sourced campaign funding, has an acute understanding of the limits of American power. Under Mr Bush, America looked to be in terminal decline. Thanks to Mr Obama, America will enjoy its superpower status for a while longer in the best possible way.
