Americans want their soldiers to vote. But often they can’t. Despite absentee balloting, military personnel deployed overseas often just cannot participate in elections.
For most of U.S. history, military personnel have not been able to vote. State laws and constitutions often specifically restricted military personnel from participating in the franchise. Attitudes about voting soldiers started to change when the Civil War called large numbers of citizens for military service—but action was tempered by partisan politics.
