Voters in Princeton Township and Princeton Borough are deciding Tuesday whether to combine their two towns.

At least three times in the past 60 years, the communities have rejected a merger.

The township surrounds the borough like a doughnut, and Ivy League Princeton University straddles the town line.

Studies have shown taxpayers in both communities could save money by joining. But skeptics fear losing their local identities.

The two towns are among 566 municipalities in New Jersey, many of them small.

The last time towns merged was in 1997 when Warren County's Hardwick absorbed Pohaquarry, population 7.
