We’ll grant that Gov. Cuomo was provoked by a pointless letter, and even that he’s right to say the Legislature will have to go along with getting more money for the MTA. Yet it’s still silly of him to try to pass the blame for the subways’ woes.

The provocation came in a public letter from state Sen. Michael Gianaris (D-Queens) and several colleagues, saying the next state budget should include new revenue streams for the agency. Cuomo’s initial reaction was spot-on: “The MTA has to be funded, great, thank you,” he said of Gianaris’ “great bolt of wisdom.” But, “the question is, how?”

The senator (like Mayor de Blasio) has pretended a new “millionaires tax” can do the job, though the idea was a nonstarter even before the federal tax bill made it even riskier to hike New York’s taxes on the rich.

But then Cuomo had to go and fault “do-nothing” state politicians for starving the agency in recent decades. There’s some truth there, but it skips over the grim fact that the stretchout of the maintenance cycle that led to the current subway woes started on his watch.

That doesn’t absolve other politicians, including de Blasio. But the hard political fact is that it’s up to Cuomo to point to the solution. All signs are that he’ll embrace “congestion pricing” for the city (which could prove to be a rational solution, or a disaster, depending in part on whether de Blasio does his share).

No one seems interested in looking for savings within the MTA budget. Neither Cuomo nor Gianaris wants to annoy the Transport Workers Union, or the construction unions now doing so well off the (massively overbudget) project to bring the LIRR into Grand Central.

It’s easier to just play the blame game.
