I have lived in the same place for 21 years where I registered and signed that registration card 21 years ago. Last year, I went to my bank to get something from my Safe deopsit box where they had my signature on file from over 20 years ago and they questioned why my signature had changed from the signature card. Ultimately with 2 forms of ID they let me get into the Safe Deposit Box.
That made me think with the hyper-partisan efforts by the Trump supporters to suppress votes of Democrats should I update my signature card for this election? So I called my Board of Elections and they said it is an easy process in NJ. They send a new voter registration card and you merely check off the box that says “signature update”
Now I have reasons other than just age why my signature has changed related to some permanent nerve damage related to spinal-neuro surgery but most people have their signature change over time so if you feel that your signature is significantly different from the time you last updated it with the Board of Elections, consider updating to make sure the Trump supporters have no cause to challenge your ballot.
