The Post today endorses Dutchess County Executive Marc Molinaro for governor — because New York needs a chief executive determined to turn this state around, not wallow in its corruption.

Eight years ago, Andrew Cuomo came to the statehouse with real promise, which is why we endorsed him in 2010. And, at first, he delivered: He passed a property-tax cap, cut other taxes, ended Albany’s perennially late budgets, appointed a Moreland Commission to take on corruption and backed charter schools.

But that was then — and the governor who initially seemed to “get it” has since grown sharply more partisan, more arrogant, more vindictive and, most significantly, more cynical.

The onetime attorney general who vowed to clean up Albany’s culture of corruption has instead become mired in it.

He jettisoned the Moreland Commission, its work unfinished, when it started looking into his office. And his administration has been roiled by repeated bribery and bid-rigging scandals that have seen several of his closest aides sentenced to prison.

Upstate remains an economic disaster, made even worse by Cuomo’s rejection of fracking and the utter failure of his “AndyLand” economic-development programs, which wasted billions while producing just a fraction of the promised jobs — but yielding massive contributions to the governor’s campaigns.

New Yorkers remain crippled by a crushing property-tax burden and crumbling infrastructure.

New York desperately needs to head in a new direction with new leadership, and Marc Molinaro can provide it.

First elected to public office at 19, he has served over two decades at various levels of state government. He has a detailed grasp of what’s wrong with New York government; his proposals, while ambitious, are grounded in realism.

He seeks to lower property taxes by 30 percent over five years, largely by shifting local mandates — including Medicaid — to the state. Rather than simply capping increases in spending, he wants to cut it.

Molinaro would reactivate the Moreland Commission, set up a permanent, independent corruption-fighting body and ban campaign donations from individuals doing business with the state.

He also says he’d focus economic development on investments in local infrastructure rather than simply handing out billions to companies with little, if any, oversight on how they spend it.

Andrew Cuomo has become a prisoner of his deep personal flaws and national ambitions and New Yorkers are paying the price.

After eight years, a change for the better is in order. Marc Molinaro can deliver it.
