NBC News, MSNBC News and Fox News have called President Obama the winner of Ohio and re-elected as President of the United States.
A roar thundered through Obama's Chicago election headquarters when Ohio was called for the president at 11:20 p.m. EST.
The victory in Ohio gave Obama 274 electoral college votes, four more than needed to win the presidency, reports CNBC.com. However, the Romney campaign had yet to concede victory as of 12 a.m. Insiders said Ohio votes were still being counted.
"This happened because of you. Thank you," Obama tweeted to supporters on Twitter.com
Earlier, Pennsylvania, Wisconsin and New Hampshire went to President Obama, according to NBC News.
President Obama also won in Romney’s home state of Massachusetts and in Romney’s boyhood home of Michigan.
NBC News reports that the Romney campaign has not conceded Ohio or the election.
Some interesting notes:
-- Republican vice presidential candidate Paul Ryan was unable to carry his home state of Wisconsin. Likewise, Romney was unable to carry Massachusetts, the state he served as governor.
-- Mitt Romney conceded defeated at 12:55 a.m. Speaking to supporters in Boston, Massachusetts, Romney said he called President Barack Obama and wished him well, thanked his supporters and running mate Paul Ryan.
