Just to let you know I’ve been reading the arguments in Dred Scott with great interest. While it seems that Blair put stock in the legal principle that asoldier took the domicile of the state where he is stationed, Blair could not easily make that argument today. Soldiers assigned to military posts are allowed to keep home state driver’s licenses and retain voting registration in their home states, which along with payment of primary taxes are the main iincidents of domicile.
That crossed my mind when I read the arguments. My first election was 1972, when I was in the navy. I registered in Long Beach, where I was stationed at the naval hospital, but I kept the same DL with my "home" address for my whole hitch. I don't remember how I filed income tax. In 1864 union soldiers were given furloughs so they could go home to vote. In previous general elections I guess military personnel just didn't vote if they were at remote stations. Since the army and navy were so small I suppose it never became an issue.
