Petee, the paper strip was from the last paper ballot before the Ivotronic touch screen machine that was just retired.
The paper ballots we are now using are numbered on the tablet that the ballots are torn from. The numbered stubs are returned to the County Election office and are reconciled with the 2 numbered books.
The number of each ballot is recorded in the signature book that every voter signs. The signature book also has a watermark in the signature space if a voter has applied for a mail in or absentee ballot and has returned the ballot.
It is impossible in Clearfield County to switch a voters ballot.
