President Barack Obama won four more years in office on Tuesday, describing his victory over Republican nominee Mitt Romney as a call to action that would help move the U.S. past the difficult times endured during the past four years and promising "the best is yet to come."
Propelled by wins in Ohio, Wisconsin and Iowa – states long touted as Obama’s “firewall” insulating him from his GOP challenger – the president won a long-fought election in which the economy, its slow pace of recovery and Obama’s management of it, became the central issue.
Emerging early in the hours on Wednesday in Chicago to the tune of Stevie Wonder’s “Signed, Sealed, Delivered, I’m Yours” the president struck an upbeat note about the challenges that lie ahead during a second term, with which he’ll have to reckon almost immediately in the next few weeks.
