I apologize if this question has been answered before; I did a search but was unable to find the answer. I currently work for the U.S. Government in Gabon, Africa. Because there are no adequate High Schools here, my daughter is attending boarding school in Chattanooga, TN. Myself and my wife are residents of Pennsylvania, and we have paid taxes there for the last 10 years. My initial thought is that we would use PA Senators and MOC, but when I look at some of the information on the various SA websites it is unclear as to whether I can do that since my daughter is technically a resident of TN (her Drivers License is from there, all of her mail goes to her there). I am a retired military officer so we have access to a Presidential nomination, but am hoping to get a clear answer on the residency issue. Thank you in advance for any help.
