Republican Assemblywoman Donna Simon has conceded the 16th district election to Democrat challenger Andrew Zwicker.

With less than 80 votes between them, Simon decided not to challenge the results of the Nov. 3 election after determining there were no voting irregularities. In a statement, Simon said, "It was my distinct honor and privilege to serve my constituents of the 16th Legislative District in the State Assembly and the people of our great State."

NJ Advance Media reported she told Zwicker of her decision via a phone call on Monday, the report said.

"I leave with a heavy heart, but with great pride in having always served with purpose, honor and integrity. I sincerely thank all who have placed their faith in me and for their continued support. God bless you all." wrote Simon, who had held the seat since 2012.

Zwicker is the head of the the science education department at the Princeton Plasma Physics Laboratory. The 16th district includes Branchburg, Delaware, Flemington, Hillsborough, Manville, Millstone (Somerset), Montgomery, Princeton, Raritan (Hunterdon), Readington, Rocky Hill, Somerville, South Brunswick, Stockton.

Her decision means Democrats picked up four seats in the Assembly in the Nov. 3 election, giving them 52 of 80 seats in the new legislative session which begins in January.
