I think the green screen/Walter Reed thing is funny to those of us who follow this campaign close enough to instantly recall the lime-green backdrop from June. But to the low-info voter tuning in last night, I thought the repeated crowd shots over three nighs of the lily white GOP delegates interrupted by the cutaway to the same African-American vet in the black POW-MIA hat during the Palin speech for example, probably sent a subliminal message to all those hispanics, blacks, Asian, Arabs (in Michigan), and all the ethnic groups in America that the Republican party is not a place you can call home.  I  thought McCain might use his speech to make a play somebody but the flag-waving Caucasions.  If he did, I missed it.
