Some New Jersey voters were left confused when they showed up to vote at their polling location on Election Day due to newly drawn congressional district maps.

News 12 was outside Kawameeh Middle School in Union Township, where new district boundaries left some confused.

“My husband and I were very surprised,” says New Jersey resident Susan Monticello.

Monticello is one of 1.4 million New Jerseyans who found themselves in a new district in this year’s midterm elections - some of whom are finding names on the ballot that they didn't expect to see.

Many voters in Union County saw TV ads for the hotly contested race between Democratic Rep. Tom Malinowski and Republican challenger Tom Kean Jr. They assumed that they would be choosing one of those two candidates as they had two years ago.

But Union Township has been moved from the 7th Congressional District to the 10th Congressional District. These voters will be choosing between Democratic Rep. Donald Payne Jr. and Republican challenger David Pinkney.

Some people learned of this change only when they got their sample ballots. But others only learned when they got into the voting booth. Voter Hugh Strong says he went looking to vote for Malinowski. He says he was surprised to see that name wasn’t here.

This is a normal part of the voting process. Districts are redrawn every 10 years when new census data comes out.

It has big implications for the Malinowski/Kean race. Union Township tends to vote Democratic. The contours of the 7th District have been shifted away from more blue areas - like Union and Franklin Township in Somerset County. It now includes Warren County, which tends to vote more red.

Malinowski won the 2020 campaign by just over 1% of the vote.
