President Barack Obama thanks Americans for giving him second term.
Moments after network predicted his victory, Obama went online to thank voters for giving him a second term.
"This happened because of you. Thank you. Four more years," Obama tweeted on his official account.
As television networks projected that Obama was on the road to victory once again, his supporters flooded the campaign headquarters in Chicago, the hometown of the President. Celebrations erupted as Democrats raised slogans and reveled in victory.
Hundreds and thousands of supporters of Barack Obama across the country from his home town Chicago to Times Square in New York erupted in celebrations.
65-year-old Romney, a businessman, had gained momentum in particular after the first presidential debate in early October.
