Obama has won... Twitter. The president's first words (on social media, at least) after being named the victor in last night's election quickly became the most retweeted of all time.

The president's tweet "Four more years," with an attached photo of him in a joyous embrace with wife Michelle, was retweeted 226,249 times in just 22 minutes. At the time of this writing, that number has climbed to 666,130. Now that's a mandate.
