American President Barack Obama rolled up victories in Wisconsin and Pennsylvania on Tuesday as voters chose between the President and Republican challenger Mitt Romney in a decision that will set the course for two starkly different visions for the country. Obama's victories in the two states put pressure on Romney to score victories in Ohio, Florida and Virginia, three battleground states where the race was too close to call. After a long and bitter presidential campaign, Americans cast their votes at polling stations across the country. At least 120 million people were expected to render judgment on whether to give Obama a second term or replace him with Romney.
