Barack Obama left Washington on a tour of swing states crucial to his re-election in November after delivering a populist state of the union speech that launched his 2012 campaign.
Obama called for a fairer, more equal America, the theme he is to pursue throughout the campaign, branding the Republicans as the party of the rich elite.
Republicans accused him of promoting "class warfare" and adopting "left-wing demagoguery".
Although Obama did not mention by name one of the Republicans chasing the party nomination to be his challenger, Mitt Romney was the president's target when Obama called for a minimal tax rate of 30% for millionaires.
"Washington should stop subsidising millionaires," the president said.
He added: "Now, you can call this class warfare all you want. But asking a billionaire to pay at least as much as his secretary in taxes? Most Americans would call that common sense." » | Ewen McAskill in Miami | Wednesday, January 25, 2012
