For this one I worked at the court house. We opened and put thro the machine the absentee ballots. There is a place on the ballot that allows people to do a straight party vote. We also did spoiled ballots. There are two types, one at the poll where the voter makes a mistake and asks for a new ballot - these are counted and discarded - and one that will not go through the scantron machine. Sometimes they used ink instead of pencil, or maybe they voted for two people for a race instead of only one. We sit at a table to reconcile these ballots. We write the number of the spoiled ballot on the bottom of the one we use to reconcile. One major problem I had was that if they voted for a straight party vote, then double voted elsewhere, the straight party vote counted. One person voted for everyone but Bush, but Gore got the vote because of the straight party vote. Some voted for all 4 of the parties using the straight party bullets. Some of the things I saw were funny, some were scary.
We have very strict rules, and voter lists are on computer to prevent double voting. It is very hard to get a name off of the lists. Someone (family or maybe neighbor) has to swear an affidavit that someone has moved or died.
