US President Barack Obama is greeted by mayor Carolyn Goodman upon arriving at the Las Vegas McCarren International Airport in Las Vegas, Nevada, on January 25, 2012. Obama kicked off a three-day five states tour, a 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 late Tuesday — 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.
