Aargh. You beat me back to the computer about Maryland. I stand corrected. Revise that to " DC residents should be allowed to vote as residents of MARYLAND which donated DC to the Federal government. "

With appropriate amendments to the US constitution, if necessary, and agreements with Maryland, the world citizens of Washington DC could and should be voting for Reps, Senators, and Presidents like the rest of us. Residents of Indian Reservations vote in elections in their states although reservations have special federal ties. DC residents, not already residents of states, should be able to do the same. If, like armed service personel, DC residents have a residence in another state, they should be allowed to vote in those states like armed service personel. I would be suprised if they can't already do that.
