You should check your voting district rules. If you state you need to vote absentee because you are out of the precinct on election day, and then you show up there on election day you aren't really out of the precinct are you? In which case they will invalidate your absentee ballot and make you vote where you should have voted in the first place - or not tell you and invalidate your ballot.
This is not good advice.....check first. For all you know this could be a trick to get you to invalidate your absentee ballot.
On election day I'm going to work. I've already voted.
