President Obama election-night tweet retweeted more than Justin Bieber’s tweet

A photo of President Barack Obama hugging first lady Michelle Obama tweeted by the Obama campaign on election night has been retweeted nearly half a million times, likely making it the most shared tweet of all time. The tweet--issued shortly before Obama was projected by several networks to be the winner of Ohio--included the image under the caption, "Four more years."

According to, the most popular Twitter message before Tuesday was a tweet by Justin Bieber for Avalanna Routh, a six-year-old fan of the pop star who died of cancer.

"RIP Avalanna," Bieber wrote on Sept. 12."i love you."

While President Obama's Twitter feed technically now holds the most popular tweet of all-time, Obama himself does not. Personal tweets from the president are signed "-bo," like the tweet, published several minutes before the photo, thanking his supporters. It read: "We're all in this together. That's how we campaigned, and that's who we are. Thank you. -bo"

That tweet was retweeted more than 141,000 times.
