What is so awesome about the baby-kissing tradition in American politics is that presidential candidates are required to kiss babies but babies are not required to conform to any social norms. They're babies, after all! Babies do not always smile back at the very people most deeply invested in getting a high quantity of baby smile photos. In Springfield, Virginia, on Thursday, Mitt Romney encountered a baby deeply unhappy with the state of American politics outside American Legion Post 176, as seen above. The screamer inspired us to browse Romney's history with the campaign trail babies who both love and fear him. What we like most is that no matter what these babies are feeling, the intensity of emotion is real amidst a staged campaign event, which is pure artifice. Keep acting like a baby, you babies.
