Sen. John DeFrancisco called the endorsement of his chief rival for the Republican nomination for governor by the state Conservative Party “disappointing” and indicated he was re-evaluating his campaign.

“It was disappointing, obviously,” DeFrancisco said Monday afternoon. “I thought I had a good record with the Conservative Party. But sometimes background and record is not as important as political analyses.”

The Conservative Party is backing Dutchess County Executive Marc Molinaro for governor. The endorsement of the party is key for any Republican running statewide, and DeFrancisco said both parties need to be united this fall.

“It’s one thinking you can win and change the direction of this state, but you have to be practical,” DeFrancisco said. “If the Conservatives and Republicans are not united, then it’s very difficult to win.”

Asked if he would continue on with his campaign, DeFrancisco wouldn’t commit to moving forward through the state Republican convention in May.

“We’ll see. It was announced today. I learned about it yesterday,” he said “We’ll explore different things, but I’m not out of it at this point in time.”

But he also has wanted to avoid a primary challenge in the Republican nominating process, as Cuomo himself faces a challenge from actress and advocate Cynthia Nixon for the Democratic line.

“I’m going to do everything I can to make sure Gov. Cuomo is retired at the end of this year,” DeFrancisco said.
