Despite federal and state probes into government pay-to-play schemes, New York’s Democrats are offering fat-cat donors access to bigwigs at the party’s national convention in exchange for contributions, The Post has learned.

In their pitch for cash, state Dems promise to grant a dizzying array of perks to top donors at the Democratic National Convention in Philadelphia in July.

“We are proud to work with you as we plan for the 2016 Democratic National Convention. With over 400 delegates and most (if not all!) of our elected officials attending, we plan to make this a week to remember,” the state party said in a fund-raising letter.

“We hope you will join us to sponsor one of our statewide breakfast receptions, a pre-convention happy hour or late-night party!”

“Empire” donors who cough up $100,000 get “VIP credentials for all convention proceedings,” along with tickets to parties and photo ops with politicians at the convention podium, four rooms at the posh Loews Philadelphia Hotel and tickets for a suite at a Yankee game with a “special guest.”

Less generous donors can be “Gold” sponsors for a $50,000 contribution, “Silver” for $25,000 and “Bronze” for $10,000. They will enjoy fewer perks but still get plenty of access to officials.

‘They’re showing no sensitivity to the way money is corrupting the political process in New York and how it crowds out the little guy.’ - Dick Dadey, head of the New York-based Citizens Union

The pols and delegates expected to attend include Gov. Cuomo, Mayor de Blasio, labor leaders and members of New York’s congressional delegation, the Legislature and the City Council.

De Blasio and associates of Cuomo are the subject of probes.

Government watchdogs blasted the solicitation scheme.

“The company that chips in with $100,000 will have one-on-one access with the presidential candidate and congressional lawmakers as well, and they are buying influence in our government,” said Craig Holman, of the DC-based Public Citizen.

“Every lobbyist and interest group sees it as a means of throwing money at the feet of elected officials. It’s one of the most offensive elements of our campaign process, an embarrassment that doesn’t pass the smell test and has never passed the smell test.”

Dick Dadey, head of the New York-based Citizens Union, noted that while the practice is legal, this year’s pitch is tone deaf to public sentiment, given the recent flurry of pay-to-pay probes.

“They’re showing no sensitivity to the way money is corrupting the political process in New York and how it crowds out the little guy,” Dadey told The Post.

“Given the backdrop of pay-to-play investigations that have engulfed New York, it seems a bit unseemly for the party to be cashing in with donors, soliciting such big contributions to get access to decision makers and policy makers at the convention.”

Basil Smikle, executive director of the state Democratic Party, offered a familiar defense: Everybody else does it.

“This is a standard sponsorship [solicitation] used by state parties across the country,” he said.

Party sources provided fliers from Democratic parties in Florida, Ohio and California soliciting similar donations.

In California, the amounts were much larger, with a $250,000 “Grizzly” sponsorship giving the donor access to parties and a golf outing among other perks.

New York’s Dems not only want the cash — they want it now.

“We suggest you secure your sponsorship TODAY as we anticipate selling the hotel out quickly,” the fund-raising letter said.
