Did you cast someone else’s ballot in addition to yours? If you cast another person’s vote, in Georgia it is legal if you are the other person’s “mother, father, grandparent, aunt, uncle, brother, sister, spouse, son, daughter, niece, nephew, grandchild, son-in-law, daughter-in-law, mother-in-law, father-in-law, brother-in-law, sister-in-law or an individual residing in the household of such elector.” These laws vary from state to state. New York does not have specific laws on the subject although there is a bill pending in the State Assembly to put some restrictions on absentee ballot collections.
The comparison of the manual and computer recounts in Georgia from the November election shows that you do not have to worry about your vote being changed.
