State Senate Democrats crying foul over former Mayor Ed Koch’s New York Uprising campaign should stop their whining.

They think it’s unfair that Koch’s group branded their Senate leadership as “enemies of reform” while all 29 members of the Senate GOP were hailed as “heroes.”

But Koch’s labels, though a bit harsh and simplistic, were issued fairly and honestly.

And if Dems don’t like his judgments, they have no one but themselves to blame.

Like every other candidate for state office, the Senate’s top leaders – including Democratic conference chief John Sampson, Temporary President Malcolm Smith and Finance Committee Chairman Carl Kruger – were challenged to pledge support for Koch’s three-point reform plan.

They chose not to sign.

Koch’s plan calls for basic good-government fixes that virtually every nonpolitician in the state recognizes as good ideas. It would abolish the rank, partisan gerrymandering of legislative districts that quashes competitive elections; beef up ethics enforcement to root out rampant corruption at the Capitol, and impose budget rules to assure responsible, open handling of tax dollars.

These are exactly the kinds of proposals that Senate Democrats promised only two years ago, when they were still in the downtrodden minority – but didn’t deliver when they finally got the chance.

Now, they’re not even signing a pledge that would commit them to do better in the future.

Sampson’s team has made some improvements since taking over, such as giving rank-and-file members and committees marginally more influence over what bills come to the floor for a vote. They’ve also posted their payrolls and other internal details online.

But on the all-important issue of redistricting, Smith had this to say in May: “We are going to draw the lines so that Republicans will be in oblivion in the State of New York for the next 20 years.”

And Sampson promised that nonpartisan redistricting would be put to a vote this year. Never happened.

Which is why Sampson, Smith and Kruger richly deserve Koch’s “enemies” tag.

Ditto for Assembly Speaker Sheldon Silver and other Democrats in his house. They passed an ethics reform bill that exempted lawyers (including Silver) from full disclosure of their outside income, which was rightly vetoed by Gov. Paterson. And Silver is on record opposing independent, nonpartisan redistricting.

That said, the “heroes” label – given to the GOP leadership – is not a good fit for Sen. Dean Skelos & Co. No one should forget what the Senate was like when Republicans ran things.

They gerrymandered ruthlessly – with Skelos himself running the panel that twisted the district lines.

They co-authored decades worth of reckless budgets that spawned the massive deficits of today.

And they allowed corruption to flourish – to the point that Senate GOP leader Joe Bruno was indicted by the feds shortly after leaving office.

Bruno’s conviction may well be overturned, but the evidence that he ran his private business out of his Senate office – and took huge fees from businesses seeking his favors as Senate boss – remains unrefuted.

Skelos & Co.’s signatures on a reform pledge cannot wipe away that sorry record.

Another bad fit for the H-word is Pedro Espada of the Bronx, a Democrat infamous for flouting campaign finance rules and, according to charges from Attorney General Andrew Cuomo, looting $14 million from his chain of health clinics.

Word choice aside, though, the fact remains: Skelos and his members have at least promised, in writing, to support critical reforms. Sampson and Silver did not. The voters should draw their own conclusions.
