Mayor Bloomberg this week unloaded on Gov. Cuomo’s ill-advised decision to strip the city of its power to finger-image food-stamp applicants.

“When Albany decides to micromanage the city, it’s not always good,” the mayor complained. Quite correctly.

When the state dropped the requirement for all other municipalities in 2007, the city — with the state’s largest food-stamp caseload — was granted an exemption.

The mayor noted that finger-imaging saves money by identifying duplicate, potentially fraudulent, beneficiaries.

So why interfere with the city?

“We shouldn’t treat the poor or the hungry as criminals,” Cuomo says.

Which is nonsense on its face.

You can’t go to work for the city without submitting to finger-imaging. Why should those applying for welfare get a pass?

Of course, there is a (very large) wing of the Democratic Party that believes that no disapprobation should attach to living off the sweat of someone else’s brow.

So far, Cuomo has pretty much kept his distance from those folks — and it is devoutly to be hoped that his action here isn’t the beginning of a trend.

Bloomberg, for his part, promises that the city won’t stop working to guarantee that people are who they say they are when applying for food stamps.

Finger-imaging was the fastest way of validating eligibility.

Alternate background checks add more time — and city money — to the process.

To be sure, Cuomo claims that his new computerized statewide system will be cheaper and more effective.

New Yorkers have heard that before. And now all they have is another expensive — but unfunded — mandate from Albany.

Happily, it’s not too late to save the day.

A 45-day public-comment period before the finger-imaging takes effect begins Wednesday.

Plenty of time, then, for the governor to come to his senses.
