US President Barack Obama swept to re-election on Tuesday, creating history again by defying the undertow of a slow economic recovery and high unemployment to beat Republican foe Mitt Romney.



Obama became only the second Democrat to win a second four-year White House term since World War II, when television networks projected he would win the bellwether state of Ohio where he had staged a pitched battle with Romney.
