Guess who else gave birth yesterday aside from Kate Middleton and approximately 370,000 other people? Mitt Romney's daughter-in-law! It may seem like Mitt Romney is merely pointing out in the above tweet that the baby is his 22nd grandchild, but "#22" is actually what he plans on calling the boy from now on. Every grandkid gets a number and a corresponding row on Romney's "Who Are My Grandchildren?" spreadsheet.
