Why not use her look alike Ann Romney to stand in as her double? Nobody can tell the difference between the two and nobody would notice that Brewer is missing. I think Brewer and Ann Romney are identical twins at birth.
Rumor is that she is in Afghanistan boosting the morale of white American troops. Maybe she brought presents designed to encourage any non-white US military personnel to move to Tejas, Californication, or anywhere but The-Arid-Zone. All IMHO.
And Mark Sanford went hiking on the Appalachian Trail.
The only source of info that Brewer went to Afghan is a statement from one of her staff. There is no confirmation of her visit by Afghan news media. Is she there on an incognito basis? Why the shroud of secrecy on the visit, especially for a publicity hound like Brewer. Doesnt make sense.
