Obama campaign says it won Florida

Two days after he was re-elected President of the United States, Barack Obama's campaign said on Friday he has won 29 electoral college votes in Florida, the only state which had not declared a winner on Election Day.

Republican challenger Mitt Romney's campaign too conceded defeat in Florida, a key battleground state.

With the win in Florida, 51-year-old Obama's tally reached 332 against Romney's 206. In the 2008 presidential elections, Obama, the first black American to occupy the White House, had secured 358 votes.

In the state-by-state electoral college system, a candidate needs 270 votes for victory and Obama already had 303 before Florida was called.

"On behalf of Florida Democrats, I wish President Barack Obama congratulations on his re-election and on winning Florida's 29 electoral college votes," Florida Democrats chair Rod Smith said in a statement.

After the counting of votes, Florida was declared too close to call as Obama had received 49.9 per cent of the total votes as against 49.3 per cent of Romney, forcing election officials to count the thousands of provisional and absentee ballots.

"We feel we will be the official winner in Florida," Obama campaign manager Jim Messina told the Miami Herald as the lion's share of the outstanding ballots came from the Democratic stronghold of the State.

According to latest figures, Obama's lead was 58,055 votes, which according to the daily was unbeatable.

Romney's Florida campaign acknowledged that their candidate lost in the Sunshine State as well.

"The numbers in Florida show this was winnable," Brett Doster, Florida advisor for Romney, told the daily.

"We thought based on our polling and range of organisation that we had done what we needed to win. Obviously, we didn't, and for that I and every other operative in Florida has a sick feeling that we left something on the table. I can assure you this won't happen again," he said.

At this stage, any Romney victory in Florida would not have had any impact on Obama's win.
