Do not make corrections on anything a voter wrote. That will make the signature invalid. If you know the voter, you can let them go back and fix an error, but petition circulators may not fix or change anything for the voter. It’s important that the entry is legible, so the county workers can compare it to the voter rolls and verify that the person who signed is a registered voter at that address in that county. If you’re not sure it’s correct or clear, you may cross it out—use a pen or marker to draw a line through the name, address and signature lines in that signature block, and have the voter sign again.
