 Earlier this year, a law was passed permitting in-person early voting in New Jersey. All registered voters can now cast their ballot in person, using a voting machine, during a nine-day period prior to Election Day. You can choose to vote when it's most convenient for your schedule.

 Five Things to Know About Early Voting

No matter where you live in Mercer County, you can vote your specific ballot in-person at any of our county's eight designated in-person early voting locations, from Saturday, October 23 through Sunday October 31.  Monday through Saturday, 10AM - 8PM and Sunday 10AM - 6PM.  

Early voting sites are as follows:

If you always vote by mail, but now want to vote early in person, instead, you must opt-out of Vote by Mail with your county clerk by August 31, 2021. If you opt-out after this deadline, you will not be able to vote in a voting machine for the upcoming election and will have to vote on a PROVISIONAL BALLOT.  You may opt out for FUTURE elections by filling out this form.
