New York Republican Chairman Ed Cox on Wednesday criticized Gov. Andrew Cuomo’s “personal politics” that has motivated his feud with New York City Mayor Bill de Blasio and led him to push for policies such as the $15 minimum wage proposal.

“Governor Cuomo is desperate politically,” Cox said on Fred Dicker’s Talk-1300 radio show. “He’s doing everything that is political expedient for himself.”

The comments come amid the deepening rift between the governor and mayor, Democrats both whose hostilities are now in the open after de Blasio in July blasted Cuomo in a NY1 interview for siding with Senate Republicans at the expense of the city’s agenda in Albany.

On Tuesday, de Blasio appeared with Cuomo’s Republican opponent in his 2014 re-election bid, Westchester County Executive Rob Astorino.

Cuomo, meanwhile, knocked de Blasio for standing with an elected official who holds conservative views on abortion, same-sex marriage and the Syrian refugee debate.

“I do recall in September he stood between the pope and Cardinal Dolan,” Cox said of Cuomo. “I believe both of them are staunchly pro-life.”
