Marc Molinaro, the Republican nominee for governor, vowed Wednesday to put an end to relentless pay-to-play politics and public corruption in Albany if he gets elected.

“Albany will not be a cash cow for the rich and powerful any longer!” declared Molinaro, drawing cheers from a sparse but vocal crowd at the state Republican Convention in Midtown.

Minutes earlier, he had unanimously scored the GOP designation to run for governor.

“We will not be an ATM for out-of-touch politicians anymore. Not for the big-money donors; not for politicians looking to dole out billion-dollar political favors. Not when I’m governor! The pay-for-play schemes, this New York fire sale ends!

“We need to work together to shake the yoke of corruption from our backs, to throw off the never-ending burden of a government that spends more than it should, taxes more than we can afford, and mortgages our children’s futures,” he added.

The Dutchess County executive said if elected, he would “immediately impanel a real Moreland Commission to follow the corruption, uncover the crimes and bring offenders to justice.”

Molinaro also promised to boost state ethics laws and put an end to “no-bid contracts.”

He accused Gov. Andrew Cuomo of using the governor’s seat as a potential steppingstone to run for president.

Molinaro also said term limits are needed in state government and vowed to serve no more than two four-year terms, and ultimately put the issue of term limits before voters to decide.

Molinaro was introduced by former Gov. George Pataki, the last Republican to hold the post after defeating Cuomo’s dad, Mario, in 1994.

Pataki called Albany “the most corrupt capital in the United States” and “an embarrassment.”

Molinaro, 42, was elected Dutchess County executive in 2011. He was first elected to public office at the age of 18 in 1994, serving on the Village of Tivoli Board of Trustees. He was then elected mayor of Tivoli in 1995 — making him the youngest mayor in the United States.
