Proponents of the consolidation measure asserted that when the merger is completed, the new municipality of Princeton will save $3.2 million as a result of some scaled-down services, including layoffs of 15 government workers, including 9 police officers (however, the measure itself does not create any line item cost reduction or layoffs).

Opponents to the consolidation measure asserted that cost savings alleged by a widely circulated report were incorrect and/or unsubstantiated and that individual voter representation would be diluted by the merged municipal structure.
