Conservative Party Chairman Mike Long told Fred Dicker on his Talk-1300 radio show Wednesday morning that he believes Westchester County Executive Rob Astorino was seriously considering a run for governor, though he urged Republican leaders to not dismiss Carl Paladino’s threat of running out of hand.

“I think he’s dead serious about running for governor,” Long said in the interview.

Astorino’s candidacy would likely excite the Republican establishment in the state, and GOP leaders were buoyed by his resounding re-election victory in the suburban county last week.

Astorino so far has done little temper talk that he’s interested in running. He attended the Somos el Futuro conference in Puerto Rico over the weekend.

On Sunday, he spoke with Long by phone to discuss a potential statewide campaign and also to give the chairman a heads up on Dicker’s Monday column in which he dips his toe into the race.

The monkey wrench that could be thrown into the plan, of course, is Paladino, the 2010 gubernatorial nominee who Cuomo defeated in a landslide.

Paladino wants to boot the party’s conference leaders in the Senate and the Assembly or he would launch his own bid on the Conservative Party’s Row C, a move that would almost certainly split the party’s vote and potentially knock the Republicans off Row B.

Though Long wouldn’t commit to either Paladino or Astorino, he that when he comes to the Buffalo businessman Republicans “would be wise to listen to his voice.”
