BLACK AND WHITE VERSION - A supporter cries as she listens to US President Barack Obama address a campaign event at the University of Illinois at Chicago in Chicago, Illinois, on January 11, 2012. Obama sought to strike an implicit contrast with his most likely general election foe Mitt Romney, imploring big businesses to bring home US jobs outsourced overseas. White House officials insist that Obama has not yet started to focus on his bid for a second term in November, but is instead concentrating every day on his job, which he sees as reviving the economy and cutting unemployment.

BLACK AND WHITE VERSION - A crowd of people photograph US President Barack Obama speaking at the Intel Ocotillo Campus in Chandler, Arizona, on January 25, 2012. Obama kicked off a three-day five-state tour, one day after his State of Union speech. Obama wants large tax hikes on millionaires to finance a fair economy for all, a populist vision aimed at convincing crisis-weary voters he merits a second White House term. In his annual State of the Union address -- which this year served as a grand kick-off of his 2012 reelection campaign, Obama played on rising anger over inequality in the wake of the 2008 economic collapse.
