The New Republicans are victorious again in Northfield — this time with the backing of the city and county party.

New Republicans Jim O’Neill and John Dunn defeated incumbent Republicans Tim Carew and Tom Polistina for the at-large and 1st Ward seats, respectively.

O’Neill, currently a 2nd Ward councilman, defeated three-term councilman Carew for the at-large seat by an unofficial count of 455 to 290, not counting provisional or mail-in ballots.

Dunn defeated Polistina by an unofficial vote of 186 to 131.

With fellow New Republican Greg Dewees running unopposed in the 2nd Ward, the winning streak of the New Republicans continues following the initial wins of O’Neill and Council President Lisa Brown in 2011 and Jim Travagline in 2012.

This year, the New Republicans gained the endorsement of the city Republican Committee, and with it the endorsement of the county party and the right to run on the Regular Republican line in the primary.

“It was a great election, and Tim was a great opponent,” O’Neill said. “I want to thank him and his family, and I want to thank all of my supporters and the New Republican Club. I look forward to the race with Frank Perri in November.”

O’Neill will face Democrat Frank Perri, also a current ward councilman, for the at-large seat in the fall election. Dunn will face Democrat Paul Utts in the 1st Ward, while Dewees will face Democrat Gerard McGee in the 2nd Ward.
