U.S. President Barack Obama’s Twitter message saying “four more years” has become the most retweeted post ever.

U.S. business magazine Forbes reported that the U.S. president’s message was retweeted more than 650-thousand times as of Wednesday morning, local time, breaking the previous record of 223-thousand set by pop star Justin Bieber in late September. Obama tweeted it Tuesday night, right after media reports came about his victory in Ohio.

Forbes said that the record is another victory for Obama, who overwhelmed his Republican rival Mitt Romney in social networking campaigns.
