Early voting

I passed by a "Vote Early" sign today and it got me to thinking. Early voting sounds like a good idea. It allows people time to get to the polls and vote, especially if they know ahead of time they won't be able to make it on election day or if they need special assistance. All kinds of good reasons to do it. In fact, I even voted early in the state's January election. However, just thinking out loud, but what happens if somebody goes to vote early and then something tragically happens to that person. Therefore, they aren't even alive on election day. Isn't that tantamount to dead people voting? Anyone got a good response to my thought?
