In fact, another crucial question to ask is whether Mitt Romney explicitly states such a racial contrast (between “us” and “them”) by using first- and third-person language. Does he talk explicitly about “us,” “we,” or “our?” And, if so, based on the images of those portrayed in the ad, are “we” most or all white?
In the same "good and decent Americans" ad from question No. 3, the imagery of all-white supporters surrounding Romney helps to clarify who “we” and “us” are, and implies who “they” are. If “we” are all white, by virtue of those pictured in the ad, then “they” – those who don’t love America, and so on, could be interpreted as those who are not white.
