Think McCain's "one of us"? Maverick? Regular white guy? Think (not think again, as you obviously have not been thinking at all).
Of course, many voters believe that Barack Obama is a Muslim, not an American citizen, hates America, is nazi and a communist, and wants to kill little babies so he can eat them, so I guess the chasm between McCain's election image and his real image is not their concern.
Also, according to Bush's definition of torture, McCain was not tortured as a POW. You can't have it both ways.
