An Irish couple are really allowing politics to divide their family — by running against each other in an upcoming general election.

Mayor of County Cork Christopher O’Sullivan is standing for the centrist Irish republican party, Fianna Fáil, against his Social Democrat girlfriend Holly Cairns in a battle for a seat in the Irish Assembly.

“I feel like I’m in a badly-written rom-com,” Cairns told The Southern Star newspaper in County Cork.

“Obviously, we get on like a house on fire personally, not so much politically,” she said.

“All’s fair in love and war. Bring it on.”

O’Sullivan insisted that their relationship is strong enough to deal with the duel for the same seat in the Feb. 8 general election.

“We have a great relationship and I’m absolutely mad about her,” he told the paper, insisting his now-rival was “a fantastic candidate.”

“We get on well but we differ politically,” he said, adding, “I wish her the best of luck.”
