World leaders have historically telephoned each other to offer congratulations following electoral victories. These days, they take to Twitter to do it, in an even more public fashion.
Before President Barack Obama had delivered his victory speech, he’d already been tweeted at by some of the other leaders of the free world.
Among them, UK Prime Minister David Cameron:
Warm congratulations to my friend @barackobama. Look forward to continuing to work together.— David Cameron (@David_Cameron) November 7, 2012
