This is one of those reports that doesn’t really make you blink when you think about how corrupt politicians in New York state are, but is still fundamentally shocking.

The New York Post reports that Senate GOP leader Dean Skelos and other Republicans cut a deal with Governor Cuomo, providing their support in the governor’s re-election bid in exchange for him staying out of races on Long Island.

The state’s most powerful Republican secretly worked for months to help Democratic Gov. Andrew Cuomo win re-election — in exchange for Cuomo’s promise not to aid Senate Democrats in their Long Island races, a top New York GOP leader has charged.

Former state Republican Party Executive Director Michael Lawler — who managed Rob Astorino’s ill-fated gubernatorial run against Cuomo — told The Post that he learned of the alleged bombshell deal between Senate GOP leader Dean Skelos and Cuomo just days ago, after suspecting for months that it existed.

“Dean Skelos clearly was working against Rob’s campaign — he and the governor cut a deal,’’ seethed Lawler, a protégé of GOP Chairman Ed Cox.

The Nassau County-based Skelos and his aides “fight for nothing, stand for nothing except staying in power,’’ Lawler charged.

The secret pact was revealed by Nassau County Executive Ed Mangano, a Republican and Skelos ally who originally claimed he’d be supporting Astorino, but ultimately stabbed him in the back by endorsing Cuomo.

When Republican Party Executive Director Michael Lawler called Mangano, he was told to call back “when this is over.”  Just after the election, Lawler called and was told the details of the pact between Skelos and Cuomo.

This isn’t the first evidence that Republicans worked to secure their own party’s suicide in the governor’s race.

New Jersey governor Chris Christie seemingly had an agreement with Cuomo to not discuss either man’s ethic’s problems.  Christie remained silent on the race, aside from calling Astorino’s campaign a “lost cause.”  He is the head of the RGA, a group who lists it’s primary mission as helping “elect Republicans to governorships throughout the nation.”

A U.S. News & World Report investigation also revealed that three primary consultants to Christie’s RGA also run “a well-heeled and well-funded group called ‘Republicans for Cuomo.’”
