Romney speaks around the edges in oblique or obtuse terms.
And he almost always responds with a condescending chuckle in his voice. I imagine that his advisors believe that to be Reaganesque. But Reagan would chuckle at the beginning of his response, indicative of an attitude of "I'm so glad you asked that" and then lose the chuckle and turn serious to answer. Romney, however, maintains the chuckling undertone throughout his response. This is either due to nervousness or to a kind of paternalistic attitude that suggests that he is astonished that these children would raise such silly questions, but he will magnanimously go ahead and answer them—though he seldom really does.
